GEOMETRICALLY-NON-LINEAR ANALYSIS OF STRESSED-STRAINED STATE OF MEMBERS OF TUBINGS

There the study objects are the curvilinear tubes and the tee-joints, which are the critical members of tubing systems. The purpose is to study the stressed-strained state of thinwalled members of tubing in the geometrically-non-linear statement. The design algorithms of stressed-strained state of shells in large elastic displacements have been developed by the method of finite members. The non-linear stressed-strained state of curvilinear tubes of different shapes of cross-sections and tee-joints in the action of bending moments and internal pressure has been studied for the first time. The design results of curvilinear tubes have been used in development of Industrial StandardAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
