The department of “Mechanics – Structural Mechanics and Analysis” (SMB) represents an exciting combination of experimental and computational aspects of mechanical engineering. This research and teaching field plays a crucial role in modern mechanical engineering and becomes more and more important in view of digitalization processes entering all fields of manufacturing, logistics and product lifetime. The investigations in this direction enable an efficient simulation of complex structures under various, often extreme conditions, as well as the application of sustainable and recyclable materials and their efficient exploitation. The novel strategies such as multiscale simulations, isogeometric analysis and machine learning open up new horizons: On the one hand, the structural response enables one to go deep into the material microstructure and to optimize it according to the specific external requirements. On the other hand, data-driven computation along with the sophisticated structural elements move the limits of the contemporary finite element analysis towards a more user-friendly software that is highly flexible with regard to the range of application.

We welcome two new student assistants at our department


Name: Karim Taha

Course of studies: Bachelor Mechanical Engineering

Why Mechanical Engineering?
My interest in engineering topics was awakened as a child. I was amazed how engineering affects everything in our lives. At school, I always chose the engineering subjects and I enjoyed learning them.  After finishing high school I attended the "Studienkolleg" and I learned more about mechanical engineering and its wide spectrum. With the help of mechanical engineering one could see the world from the perspective of the combination of technical progress, economic growth and social change.

Why did I apply at SMB?
As a bachelor’s student in the 3rd Semester, i realized it is the time for new challenges alongside my studies and there is no better opportunity than a student assistant. SMB deals with many aspects of mechanical engineering and various research fields and there are many interesting topics that SMB works  on, so that one could combine the acquired theoritical knowledge with professional practice in the best possible way.




Name: Diego José Hernáiz García 

Course of studies: Mechanical Engineering with emphasis on calculation 

Why Mechanical Engineering? My love for the world of Engineering and Physics has followed me since a young age. I always liked the hands-on mentality of mechanical engineering and its broad spectrum of usage in all kinds of fields. May it be the incredible lightweight construction of planes to the perfectly designed forged titanium trucks of my skateboard. So, after finishing high school (Abitur) I had little doubt what I wanted to study. 

Why did I apply at SMB?  During my bachelors and currently in my masters I took several highly interesting and challenging courses offered at the department of “Structural Mechanics and Analysis”. Through these I was able to get an insight into the different fields of research. These topics inspired me to apply and to delve deeper into the world of structural mechanics.

Marc Graham started as a research associate in our department on April 1, 2022


I completed my Bachelor's degrees in Mechanical Engineering and in Arts in 2010 at Monash University in Australia and have since then been living and working in Nice, France, and in Berlin.  I joined the TU Berlin in pursuit of a master's degree in Scientific Computing and, in January, 2022 and I completed my master thesis with supervisors, Dr. D. Peschka, Weierstrass Institute, and Prof. V. Merhmann, TU Berlin/Matheon, on structure-preserving methods in viscoelastic flows.  I am pleased to join Prof. Klinge's team in the Department of Structural Mechanics and Analysis where I begin work in the calculation of effective, macro-scale properties of materials with heterogeneous microstructure. 

North German Mechanics Colloquium in Summer ''22

The Institute of Mechanics at TU Berlin is pleased to host the 148th North German Mechanics Colloquium in the summer of 2022! It will take place online on July 15, 2022. Our partner is University of Bremen.

The Colloquium for Mechanics exists since 1946 and gathers scientists from ten North German universities working in the field of mechanics twice a year.

We are happy to continue this longtime tradition!


Colloquium prgram

Professor Sandra Klinge – New Department Head


Dr.-Ing. habil. Sandra Klinge has been a professor for "Structural Mechanics and Structural Computation" (SMB) at the Faculty of Transportation and Machine Systems at TU Berlin since July of this year. The focus of her scientific work is the development of numerical methods for the simulation of heterogeneous materials. In this context, she has focused on the application of the multiscale finite element method to solve direct and inverse problems. The large computational effort, the strong nonconvexity, the determination of the global solution are only some of the issues characteristic for this research area.

Ms. Klinge completed the international master course "Comp-Eng" as a DAAD scholarship holder at the Ruhr-Universität Bochum. At the same university she did her doctorate and habilitation. Subsequently, she established her own research group as junior professor in "Computational Engineering" at the TU Dortmund University.  Ms. Klinge has numerous international collaborations especially in the field of biomechanics and of simulation of metal forming processes. At TU Berlin, Ms. Klinge will work on the further development of numerical methods such as statistical homogenization, isogeometric analysis and machine learning as well as on their practical application. TU Berlin offers an ideal environment for work at these topics due to its diversity, large number of excellent students and strong international scientific network.


Our current topics

Life time of additively manufactured Al alloys

Cyclic repeating plastic deformation of metals causes progressive damage in the material, which eventually leads to ductile fracture. To model and simulate such a complex process, a coupling of several methods and models is required. On the one hand, the phase field method is used to simulate the damage evolution. On the other hand, an appropriate material model is chosen to capture the plastic behavior under the cyclic load. The challenge is to find consistent frameworks for coupling both formulations. The proposed framework simulates the crack development in a specimen and enables to determine the lifetime of a metal alloy.


Strain-induced crystallization in polymers

Strain-induced crystallization is a phenomenon that occurs in polymers under high tensile strains. The crystallization process forms a second phase within the amorphous polymer matrix and leads to enhanced properties of the material. The in-house developed material model implemented in the finite element software depicts the evolution of the microstructure. This is a great advantage of the model since this phenomenon is not yet accessible experimentally.


Modeling of cancellous bone and of osteoporosis

The cancellous bone is a specific tissue consisting of the solid skeleton and the fluid marrow for whose laboratory investigation ultrasonic procedures are typically used. These experiments are numerically simulated in order to calculate the attenuation coefficient which is an important indicator of bone density and can be used to diagnose osteoporosis. The focus of the model is on the harmonic excitation and simulation of viscous effects. For this purpose, a formulation in the complex domain is assumed.


Simulation of the virus entry into a cell

The receptor driven endocytosis is typical of viral entry into a cell. The virus is considered as a substrate with fixed receptors on its surface, whereas the receptors of the host cell are free to move over its membrane, allowing a local change in their concentration. In the contact zone the membrane inflects and forms an envelope around the virus. The created vesicle imports its cargo into the cell. The model proposed assumes the diffusion equation along with a boundary condition requiring the conservation of binders to describe the process. Moreover, it introduces a condition defining the energy balance at the front of the adhesion zone. The latter yields the upper limit for the for the size of virus which can be engulfed by the cell membrane. The described moving boundary problem in terms of the binder density and the velocity of the adhesion front is well posed and numerically solved by using the finite difference method.
