Overordnede kursusmål:
The course will introduce the use of the commercial finite element code Abaqus where a number of non-linear problems will be addressed. The focus will be on non-linear material simulation, simulation of fibre reinforced composites, buckling simulations and crack growth predictions.
Læringsmål:
En studerende, der fuldt ud har opfyldt kursets mål, vil kunne:
Build up a finite element model in Abaqus
Understand the backgound behind and the posibilities in the finite element method
Include the effects of non-linear material models
Predict the influence of orthotropic materials
Work with ply-layup in a composite structure
Predict buckling and post-buckling behaviour of thin walled structures
Predict crack tip properties
Simulate crack growth using cohesive material laws in a finite element model
Use extended finite element (XFEM) in order to make realistic crack growth predictions
Kursusindhold:
The workload in the course will focus on the study of a number of non-linear problems which include building up, solving and evaluate the solutions from realistic finite element problems. Throughout working with the finite element exercises, important points using a commercial finite element code will be addressed. Cases involving isotropic elastic, anisotropic elastic and elastic-plastic material laws will be studied. In addition, the use of user defined subroutines will be demonstrated.
