Abstract:

The well-known, general-purpose structural analysis program ICES- STRUDL has been used extensively at M. I. T. Lincoln Laboratory since its public release in 1967. Since that original release, several updates, issued by the original developers and the ICES Users Group, have produced changes in programs and documentation. Likewise, additional development and enhancement of ICES- STRUDL have occurred at M. I. T. Lincoln Laboratory on those areas such as finite elements, dynamics, etc. specifically of interest to the Laboratory. This report describes the finite element capabilities in the M. I. T. Lincoln Laboratory version of ICES STRUDL and can therefore serve as a users manual. Sections are devoted to specification of finite element geometry, element properties, and element loading. Finite element modelling considerations are discussed and three examples are presented to illustrate capabilities often needed at the laboratory, but not described in other ICES-STRUDL documentation.
