An interface-enriched generalized finite element formulation for locking-free coupling of non-conforming discretizations and contact

We propose an enriched finite element formulation to address the computational modeling of contact problems and the cou pling of non-conforming discretizations in the small deformation setting. The displacement field is augmented by enriched terms that are associated with generalized degrees of freedom collocated along non-conforming interfaces...

A computational study of the fracture behaviour of concrete in a modified Split Hopkinson Bar test

For a numerical prediction of the response of concrete structures under extreme dynamic loading, reliable material data and material models are crucial. A modified Split Hopkinson Bar, SHB, test methodology is used to determine the material properties in tension at high loading rates which are used in numerical models simulating progressive...
