Aim of the event:
A main task in development engineering is the assessment and the strength prediction for structures or structure parts, respectively. Examples are joined and adhesive parts in autmotive industry or gasturbine industry. To perform these tasks the engineer needs both, basic knowledge in strength of materials and additional capabilities for the practical usage of commercial finite element programs.
The course provides the basics for the assessment of spatial structures with applications often occuring in modern mechanical engineering. In particular physical and mathematical aspects of strength in materials taking into account three-dimensional stress and strains states are treated. The second part of the course is concerned with the practical use of finite element programs. Particular aspects are the generation of geometries by CAE-based modules, the input of material constants, the performance of the finite-element analysis as well the post-processing and the critical assessment of the finite-element results for stresses, strains and displacements. The exercises are concerned with practical applications in car industry and gasturbine industry. The goal in each case is the FE-simulation and the assessment of real life structures taking into account the strength of the related materials.
