Formulations and Applications for Elasto-Plastic Shell Analyses
In the previous chapters linear problems have been considered but no nonlinearities were included. The increased usage of elasto-plastic analysis for plate and shell structures has given added impetus to the search for efficient and reliable plate and shell elements. For anisotropic laminated plates and shells, where the ratio of in-plane elastic modulus to transverse shear modulus can be very large, transverse shear and rotatory inertia effects assume greater importance even for span-to-depth ratios as high as 30 . Consequently, it is a worthwhile task to test the performance of the assumed strain elements in the analysis of plates and shells with anisotropic material properties.
