Abstract
An efficient meshfree analysis platform is presented for computer modeling of brittle failure in concrete structures. The stabilized conforming nodal integration is employed for the domain integration to stabilize the numerical solution and accelerate the computation. Both efficiency and stability are preserved in the same breath. A coupled elasto-plasticity and damage model is used to describe the brittle failure evolution of concrete structures. The typical strain localization phenomena resulting form concrete damage can be effectively simulated due to the non-local features of meshfree reproducing kernel approximation and stabilized integration methodology. The performance of present meshfree analysis platform is demonstrated by simulating the sliding structure failure of a concrete gravity dam.
