Pagination or Media Count:
CURSHL is a high-precision finite element for the linear static stress analysis of thin elastic shells of quite general shape. The element is a fully-conforming displacement element of curvilinear triangular form. The theoretical basis of the element is presented in fairly complete detail, and some aspects of the organization of the computer program are discussed. The performance of CURSHL is examined with regard to accuracy of numerical integration, computation time, and representation of rigid-body modes.
