<br/><br/> This research topic aim to create a stable and expandable framework of the large deformation analysis of the reinforce concrete structure. The AEM, known for the  ability to accurately simulate large deformation including crack propagation of the  reinforce concrete material is aiming for high performance computing to accommodate  the future need for more complex and sheer size of the problem. The new framework,  inspired by the original code in Fortran is redeveloped into C++ for its superior  versatility, expandability and memory management. The newly developed frame work  is integrated with cuda-based incomplete LU preconditioned conjugate gradient solver  to help solve large sparse PDE produce by AEM. The results show that redeveloped  AEM is stable, memory safe, and can solve linear elastic problem and nonlinear with  tension cracks.
