Об использовании тензора логарифмической деформации

Abstract

Отказ от гипотезы малости перемещений в механике деформируемого тела приводит к проблемам, связанным с геометрической нелинейностью, которые до сих пор не решены до конца, несмотря на свою актуальность для практических приложений. Одна из таких проблем относится к понятию логарифмической деформации. Скалярная логарифмическая деформации в ряде случаев полезна, но тензор логарифмической деформации обычно лишен смысла. The rejection of the small displacements hypothesis in the mechanics of deformable solids leads to some problems connected with geometrical nonlinearity. At present, these problems are still not completely solved despite their relevance to practical applications. One of these problems is the concept of logarithmic strain. The scalar logarithmic strain is effective in some cases but the logarithmic strain tensor is usually useless.
