The computational efficiency for analyzing the behaviour of multi-crack structures is still a challenging issue in fracture mechanics.The stiffness matrix of a super cracked element is first formulate
裂纹附近非连续场和裂尖奇异场是无网格断裂分析中需要处理的两个基本问题。前者多需引入不连续性准则如可视性准则、衍射法和透射法等；后者常采用基函数扩展或试函数增强。然而，上述两个问题均能通过对权函数的修正来进行处理。
Ductile fracture is one of the most prevalent failure modes,often found in structural components under extreme conditions.Such failure is considered as the consequence of progressive damage accumulati

In the case of arbitrary traction on the side faces of an object,a polynomial function of the radial coordinate can be employed to describe the side-face loads using the scaled boundary finite element
Due to its dual cover systems,i.e.,the mathematical cover and the physical cover,the numerical manifold method(NMM)is superior in crack modeling.In this work,the NMM is further developed to study the
