Численное моделирование испытаний дисковых образцов при термошоке в 3D постановке

Abstract

The search for additional strength reserves stimulates the development and improvement of various numerical and experimental techniques for analyzing the behavior (including crack propagation and arrest) of structural elements with cracks under thermal shock loading. Methods for testing small specimens such as precracked disk-shaped specimens have recently been developed. The results of these tests can be used to estimate the strength and durability of large-scale structures. Numerical simulation of disk-shaped specimens under thermal shock can give more information about the features of of crack initiation and propagation in materials under thermal loading.
