COMPUTER SIMULATION METHOD ANALYZING DYNAMIC MECHANICAL BEHAVIOR OF PLAIN CONCRETE AND RECORDING MEDIUM RECORDING PROGRAM THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a computer simulation method capable of precisely simulating dynamic phenomenon such as a collision against a structure using concrete as a constituent object and dispensing with an expensive dynamic test for obtaining various material constants of concrete. SOLUTION: A dynamic configuration rule of concrete is derived, and a material constant used in the configuration rule is calculated from unconfined compression strength. The configuration rule is derived by introducing strain rate effect into Drucker-Prager configuration rule which is static non-uniform plasticity hardening model. Moreover, the material constant used in the configuration rule is calculated from unconfined compression strength.
