Abstract:
The main objective of this research was to create a parallel software implementation of a numerical method for the reconstruction of strength surface of initial failure of composite material under research. Quadratic tensor polynomial criterion named after Malmeyster–Woo was used. Asymptotic averaging method or homogenization (Nikolay S. Bahvalov, Boris E. Pobedria) and finite element method were used. Software implementation was developed using graph-based technology provided in Distributed computational system GCD using Intel MIC architecture. Computational experiments have been carried out for a series of models of composite materials defined by their reinforcement schemes (“unit cells”) to obtain the slice of its strength surface. Three types of composites were considered: 3D-reinforced and 1D-reinforced. The results of calculations are presented. (In Russian).
Key words and phrases:micromechanics of composite materials, elastic and strength properties, quadratic failure criterion, homogenization, numerical methods for solving inverse problems, high performance computing, distributed systems, finite element method, the method of asymptotic averaging.
