THERMAL STRESSES AND NONLINEAR THERMAL DEFORMATION ANALYSIS OF SHALLOW SHELL PANEL

Abstract

Modern aerospace structures such as high-speed spacecrafts, missiles and engineering and nuclear structures are often subjected to severe thermal loads and reveal a clearly nonlinear response. In such situations the associated strains and stresses are usually determined from Von Karman coupled nonlinear partial differential equations extended to thermal loading in terms of transverse displacement and stress function. Although citations of several authors may be made who have employed the method, only a few is mentioned here which contains several cross-references (Chang and Jen, 1986), (Biswas, 2001) and (Mansfield, 1982).
