摘要
介绍一种新近提出的应变梯度塑性本构模型：基于细观机制的应变梯度塑性理论（ＭＳＧ）。并对它在断裂力学中的应用进行了评述。本文的讨论虽限制在形变理论范围内。
In the paper a kind of framework of strain gradient plasticity recently developed——mechanism based strain gradient (MSG) plasticity is reviewed and its applications in fracture problems are discussed. The review is confined to the deformation theory version, though the flow theory version can be parallelly constructed.
