不等厚表层硬夹心双曲夹层扁壳的热应力问题

Thermal Stress Problems of a Shallow Double Curved Sandwich Shell Having a Hard Core and Unequally Thick Surface Layers

摘要: 探讨了具有各向同性硬夹心及不等厚度表层组成的3层双曲扁壳的热应力问题采用广义变分法,在考虑各层抗弯刚度的情况下,导出了3个基本方程。此理论可用于工程设计。

Abstract: Fundamental equations are derived which govern the thermal stress of a shallow double curved sandwich shell . The shell may have a hard core and the surface layers may have unequal thicknesses. Variational procedure is used to obtain the fundamental equations .
