Inner Variable in Crack Healing Processing
-
摘要: 在連續介質熱力學框架內,以熱力學第二定律為出發點,推導出裂紋愈合耗散不等式,確定了描述裂紋愈合過程的熱力學內變量H的定義形式.裂紋愈合過程內變量的提出,不僅可以將裂紋愈合過程模型化,而且還可以建立裂紋愈合過程的演化方程和本構方程,為裂紋愈合過程的定量分析提供可能性。Abstract: According to the thermodynamics of continuous medium, the dissipation inequation of crack healing is derived from the second law of thermodynamics. An inner variable H is defined which describes the process of crack healing. Based on variable H , the crack healing process can be explained, the evolutionary equation and constitutive equations of the process can be established, and thus it is possible to analyze the process quantitatively.
