Static and dynamic stress-strain state of parallel tubes in deformable (Paperback)

The book questions are equipped with strength and stress-strain state of underground parallel structures under static and dynamic loads. Building the basis of theoretical studies of underground vibrations parallel pipelines, cylindrical bodies are exposed to seismic loads. Presents promising technique strength calculation of pipeline components. The first chapter examines the static pressure of the environment on the pipe. The environment is a homogeneous elastic body. To determine ambient pressure using a finite element method (FEM). The algorithm (MAC), a program and a computer. On the basis of programming, numerical results obtained. The obtained numerical results for two and multi-line pipes are compared with theoretical and experimental results. This chapter consists of three sections. The first section provides basic ratio FEM. In the second section shows the formulation of the problem and description of the program MAC
