1.序 Anmad等所开创的等参数壳体单元,因其考虑了横向剪切变形、无论是厚板壳还是薄板壳都能适用、而且解的精度高,所以被认为是实用性高的壳体单元之一。关于这种单元,继Anmad之后,进行了很多的研究,但是,对各向同性的情况研究的多,而对各向异性的情况研究的少。例如,Noor等把各种等参数单元应用于单层各向异性平板的解析;Panda、Reddy
1. The isoparametric shell elements created by the order Anmad et al. are considered to be highly practical shells because they take into account the transverse shear deformation. Both thick and thin shell shells can be applied and the accuracy of the solution is high. One of the body units. With regard to this unit, many studies have been carried out following Anmad. However, there are many studies on isotropic conditions and less on anisotropic conditions. For example, Noor et al. apply various equal-parameter units to the analysis of single-layer anisotropic plates; Panda, Reddy
