Project

Nonlinear fracture in structural materials – investigation of expressions of energy dissipation in failure zone via advanced experiments and modelling (GA15-07210S)

During fracture of quasi-brittle/ductile materials the energy dissipates in an extensive nonlinear area at the crack tip. This zone consists of the fracture process zone and the plastic zone. In these zones, various microme...

Modelling of soil behaviour in hypoplasticity and its comparison with elastoplastic approach (IAB2071901)

The theory of hypoplasticity represents a new approach to the constitutive modelling of soils. Contrary to common elasto-plastic models, one does not have to distinguish between elastic and plastic deformation. This seems t...
