Stress Field Problems of a Plate-Strip Having Finite Dimensions : LAP Lambert Academic Publishing : 9786139444038 : 6139444039 : 30 Jan 2019 : The problems involving non-linear effects in the dynamics of the elastic medium is one of the major subjects of the computational and applied mathematics and cannot be solved within the framework of the linear theory of elastodynamics. There is a wide range of applications for problems including initially stressed bodies in practice. For example, initial stresses occur in structural elements after manufacturing and assembly. Initial stresses are also present in composite materials. A large number of theoretical and experimental investigations had been made in this field. Almost all of these investigations were made within the framework of linearized theory of elastic waves. For the solution of the problems involving layers with finite length numerical methods are to be employed. An efficient method for such problems is the Finite Element Method.
