Плотность энергии деформации для тел с V-образными вырезами при продольном сдвиге (mode III)

Плотность энергии деформации для тел с V-образными вырезами при продольном сдвиге (mode III)

Abstract

С позиции линейной механики разрушения рассмотрены острые V-образные вырезы с произвольным углом раскрытия при продольном сдвиге (mode III). На основе сингулярных решений показана возможность использования энергетической характеристики «плотность энергии деформации» для оценки напряженно-деформированных состояний (НДС) у вершины выреза. Такая характеристика снимает проблему разных размерностей коэффициентов интенсивности напряжений V-образных вырезов, имеющих различные углы раскрытия, при прямых сравнительных оценках НДС.
