The past 20 years have seen substantial work on the modeling of ductile damage and
fracture. Several factors explain this interest.(i) There is a growing demand to provide tools …

Classical continuum models, ie continuum models that do not incorporate an internal length
scale, suffer from excessive mesh dependence when strain‐softening models are used in …

Gradient-enhanced damage models and phase-field models are seemingly very disparate
approaches to fracture. Whereas gradient-enhanced damage models find their roots in …

Fracture and Size Effect in Concrete and Other Quasibrittle Materials is the first in-depth text
on the application of fracture mechanics to the analysis of failure in concrete structures. The …

A plasticity theory is proposed in which the yield strength not only depends on an equivalent
plastic strain measure (hardening parameter), but also on the Laplacian thereof. The …

The paper analyzes nonlocal constitutive models used in simulations of damage and
fracture processes of quasibrittle materials. A number of nonlocal formulations found in the …

In mechanical engineering and structural analysis there is a significant gap between the
material models currently used by engineers for industry applications and those already …

A simple but general model for normal/shear cracking in quasi-brittle materials is presented.
It is defined in terms of the normal and shear stresses on the average plane of the crack and …

Most of the materials produced and utilized in industry are heterogeneous on one or another
spatial scale. Typical examples include metal alloy systems, porous media, polycrystalline …

There has been considerable literature over the last 20 years surrounding adaptive methods
of mesh refinement, or solution improvement, in the finite element method. Publications …
