Thermal buckling of cylindrical shell with temperature-dependent material properties: Conventional theoretical solution and new numerical method: 点击次数：; 发布时间： 2019-03-12; 发布时间：2019-03-12; 论文类型：期刊论文; 发表时间：2018-09-01; 发表刊物：MECHANICS RESEARCH COMMUNICATIONS; 收录刊物：SCIE; 卷号：92; 页面范围：74-80; ISSN号：0093-6413; 关键字：Cylindrical shell; Temperature-dependent; Thermal buckling; Numerical approach; ANSYS subroutine; 摘要：Even though the thermal buckling behavior of shells has been investigated for many years, until now the thermal buckling problem with temperature-dependent material properties still cannot be solved by the existing commercial finite element codes. Therefore, the conventional theoretical solution of the critical temperature rise of cylindrical shell with the temperature-dependent material properties is first derived in this work. Then, an innovative numerical approach is developed by introducing the bisection method and a user subroutine of ANSYS to overcome the shortcoming of existing finite element codes. The results prove that the temperature-dependent material properties have a great negative influence on the ability of the thermal buckling resistance of the cylindrical shell. As a result, the subroutine of ANSYS developed in this work provides a convenient design method for engineers to avoid the complicated theoretical calculation. (C) 2018 Elsevier Ltd.
