本文通过对软薄膜/硬基体两相材料体系的平头压痕弹塑性模拟.重点研究了平压头压入过程中,不同屈服强度比(软薄膜屈服强度与硬基体屈服强度之比)以及不同压头尺寸下硬基体对压痕规律的影响.研究发现硬基体对压痕规律的影响与屈服强度比近似满足线性关系,且这种线性关系不随压头尺寸的改变而改变,相同压头半径下,屈服...

A model of derivatized moving reaction boundary (MRB) is formulated from original MRB formed with formic buffer (phase α) and sodium hydroxide (phase γ). The model shows the formation of a new phase (phase β) with high pH value originated from phase γ, derivatized MRB created with phases α and β, as...
