The s ‐version of the finite element method is developed for laminated plates and shells. By this technique the global domain is idealized using 2‐D Equivalent Single Layer model. The regions where ESL model errs badly in capturing localized phenomena are superimposed by a stack of 3‐D elements. Assumed strain formulation and selective polynomial order escalation in the two models, as well as fast iterative procedures, are employed to maintain a high level of computational efficiency.
