Abstract: Abstract This work investigates plastic deformation around non-metallic inclusions in rolling contact fatigue applications. Subsurface stresses from Hertzian theory are applied in form of far-field loading on an elasto-plastic micro-mechanical model of an isolated inclusion.… read more here.

DOI: 10.1177/1687814019829982
Abstract: The plasticity models in finite element codes are often not able to describe the cyclic plasticity phenomena satisfactorily. Developing a user-defined material model is a demanding process, challenging especially for industry. Open-source Code_Aster is a… read more here.

DOI: 10.3390/met10060781
Abstract: In numerical simulations of components subjected to low-cycle fatigue loading, the material cyclic plasticity behavior must be modelled until complete stabilization, which occurs approximately at half the number of cycles to failure. If the plastic… read more here.
