Discrete models of solids have been motivated, in large part, by the discontinuous and
heterogeneous nature of material structure and its breakdown under loading. The …

Many modern engineering structures are composed of brittle heterogenous, or quasibrittle,
materials. These include concrete, composites, tough ceramics, rocks, cold asphalt mixtures …

Continuum finite element (FE) modeling of damage and failure of quasibrittle structures
suffers from the spurious mesh sensitivity due to strain localization. This issue has been …

Spurious mesh sensitivity is a major challenge in continuum finite element (FE) simulations
of damage and fracture of quasibrittle structures. It has been shown that the existing …

Stochastic phase-field models can reproduce the nonlinearity and randomness of the
mechanical behavior of quasi-brittle materials within a unified macroscopic continuum …

In this paper, a stochastic phase-field model is presented to simulate the nonlinearity and
randomness of the mechanical behaviors of quasi-brittle materials within a unified …

Numerical simulations of concrete fracture performed with a probabilistic mesoscale discrete
model are presented. The model represents a substantial part of material randomness by …

Abstract The Static and Dynamic unified Size Effect Law (SD-SEL) captures the combined
effects of strain-rate and structural size on the nominal strength of concrete, and it can …

The mechanical properties and failure modes of concrete are affected by strain rate.
Therefore, various experimental methods have been used to quantify the strain-rate …

This paper is aimed at investigating the mesh objectivity in dynamic fracture analyses
employing strain rate dependent damage evolution as the localization limiter. Specifically …
