摘　　要：对梁板壳的线性理论、近似几何非线性理论与有限变形理论作了比较,介绍了有限转动理论,指出了应用有限变形理论求解梁板壳的大变形问题的高效率、高精度的巨大优越性.The linear and approximate non-linear as well as finite deformation theory of beam, plate and shell are compared. The finite rotation theory is introduced. It is pointed out that by using the finite deformation theory to solve the beam, plate and shell problems, the high efficiency and high precision can be achieved.
