The book "Solution of Crack Problems" deals with the numerical solution of crack problems in materials. It provides a detailed analysis of techniques that are particularly suitable when cracks are relatively short and develop near stress-enhancing features. These conditions lead to a steep stress gradient, allowing for an idealized representation of the geometry to obtain precise solutions. Unlike conventional methods such as the Finite Element Method, which require exact modeling of the geometry, this book offers alternative approaches based on the work of Eshelby and others. The techniques presented utilize the superposition of the stress field of an undamaged body and an unknown distribution of strain cores to create stress-free crack surfaces. The described solution techniques are efficient and enable the modeling of crack development in two or three dimensions. The book is aimed at both engineers and researchers interested in the advancement of these methods.
