Parallelized implementation of a 3D probabilistic explicit cracking model for concrete

Abstract

This paper reports the employment of parallelization techniques in the implementation of a 3D probabilistic explicit cracking model for concrete. The mentioned model is based on the use of interface elements to explicitly represent cracks and naturally has a high computational cost, which justifies the importance of developing parallelization strategies to accelerate the analyses. Parallelization was considered in the most time-consuming tasks in the finite element code: assembly of the stiffness matrix and residual force vector, and solution of the linear equation system. The results show that significant reductions in simulation time can be obtained with the parallelized code.
