Modelling dynamic tensile failure of quasi-brittle materials using stress-enhanced nonlocal models

The development of realistic numerical tools to efficiently model the response of concrete structures subjected to close-in detonations and high velocity impacts has been one of the major quests in defense research. Under these loading conditions, quasi-brittle materials undergo a multitude of failure (damage) mechanisms. Dynamic tensile failure...

Nonlocal Damage Models for Concrete

An understanding of response of concrete structures to impact loading is of interest to the Explosions, Ballistics and Protection department of TNO. Numerical simulations conducted to study this response require very small elements to capture the shockwave propagation and the material response which were found to be mesh dependent. The goal of...
