The surface-forming energy release rate based fracture criterion for elastic-plastic crack propagation and interpretation on paradox of Rice

Submitted by Bin Liu on Mon, 09/07/2015 - 03:11

The J-integral based criterion is widely used in elastic-plastic fracture mechanics. However, it is not rigorously applicable when plastic unloading appears during crack propagation. One difficulty is that the energy density with plastic unloading in the J-integral cannot be defined unambiguously.

Predicting fracture energies and crack-tip fields of soft tough materials

Submitted by Teng zhang on Wed, 09/02/2015 - 01:09

Soft materials including elastomers and gels are pervasive in biological systems and technological applications. Whereas it is known that intrinsic fracture energies of soft materials are relatively low, how the intrinsic fracture energy cooperates with mechanical dissipation in process zone to give high fracture toughness of soft materials is not well understood. In addition, it is still challenging to predict fracture energies and crack-tip strain fields of soft tough materials.
