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.

This month’s blog focuses on one of the most common kinematic assumptions in the continuum mechanics of finite elasto-plasticity: the multiplicative decomposition . This expression decomposes multiplicatively the deformation gradient of the body  into to the elastic () and plastic () deformation tensors; and it will be discussed here in the context of dislocation mediated plastic deformations.
