An embedded crack model for failure analysis of concrete solids
Abstract
We present a quadrilateral Önite element with an embedded crack that
can be used to model tensile fracture in two-dimensional concrete solids
and the crack growth. The element has kinematics that can represent
linear jumps in both normal and tangential displacements along the crack
line. The cohesive law in the crack is based on rigid-plasticity with softening. The required material data for the concrete failure analysis are
the constants of isotropic elasticity and the mode I softening curve. The
results of two well known tests are presented in order to illustrate very
satisfying performance of the presented approach to simulate failure of
concrete solids.
