Computational aspects of stress wave propagation problems
Dispersion in time and space due to finite element modelling
Pitfalls of FE computing pitfalls of FE
Examples - academic:
- Fitting experimental data, 1D stretch experiment with rubber
- 1D rod element for large strains
Examples - more practical:
- Numerical modelling of axially impacted rod
- Rock drilling efficiency revisited
Final joke:
Polution-free energy production by a proper misuse of finite elements
