在非弹性变形固体力学的许多问题中,结构构件的蠕变(尤其是薄壳的蠕变)占有显著的地位,并具有越来越大的意义。这同机器零件或设备上的力及温度的作用加大有关,也同现代技术中广泛使用轻合金、塑料以及其它人造材料有关,这类材料在常温或温度稍许提高时都显出蠕变。最近,壳的蠕变理论作为非线性变形体力学的比较年青领域得到了重大发展。
Among many problems of inelastic deformation mechanics of solid, the creep of structural members (especially the creep of thin shells) occupies a prominent position and has a greater and greater significance. This is related to the increased use of force and temperature on machine parts or equipment and is also associated with the widespread use of light alloys, plastics and other man-made materials in modern technology that exhibit creep at room or slightly elevated temperatures. Recently, the creep theory of shells has been greatly developed as a relatively young area of nonlinear deformation mechanics.
