WMC at the Fifth CFRAC

Wieringerwerf, 27-06-2017.

The fifth edition of the International Conference on Computational Modeling of Fracture and Failure of Materials and Structures (CFRAC) took place from 14 to 16 June in Nantes, France. CFRAC is part of the conference cycle of the European Community on Computational Methods in Applied Sciences (ECCOMAS) and is a forum for state-of-the-art numerical methods for failure modeling.

WMC researcher and PhD student Iuri Rocha attended the conference with the work entitled "Multispatial/multitemporal homogenization analysis of hygrothermal fatigue in glass/epoxy composites". The work presents a novel constitutive model for epoxy incorporating viscoelasticity and viscoplasticity and made efficient through time homogenization and Model Order Reduction (MOR).

The model is capable of correctly reproducing viscous phenomena arising when epoxy is tested in fatigue, such as ratcheting, stress relaxation and hysteresis. After calibration, it can be incorporated in multiscale numerical models to simulate the effect of hygrothermal cycles combined with fatigue loading. Two journal papers on the subject are currently in preparation.
