固体破坏理论的若干问题

本文列举和初步探讨了位于当代固体破坏理论的前沿上的十五个问题。它们包括：固体破坏理论的封闭、宏微观非线性力学、尺度效应、多层次计算、细微观实验力学技术、断裂过程区的描述、异质体的强度与韧性、材料的多层次抗破坏设计、高速破坏过程、非均匀介质的动态断裂与前兆、疲劳的起源、破坏元技术、内损伤破坏与微结构形貌演化失稳的识别、材料的微结构演化、电致失效力学。

OUTSTANDING PROBLEMS IN THE FAILURE THEORY OF SOLIDS

The present paper lists and explores 15 current research issues in the frontier of the failure theory of solids. They include: the missing link in the failure theory of solids, combined macroscopic-microscopic nonlinear mechanics, scaling effects, computations in multiple-scales, experimental mechanics in small scales, formulation of a fracture process zone, strength and toughness of heterogeneous bodies, multi-scale failure-resistant design of materials, high strain rate failure processes, dynamic fracture and precursor of heterogeneous media, origin of fatigue, failure elements in computations, recognition of intrinsic damage patterns and morphological instabilities, structural evolution in materials , failure mechanics under electric fields.
