Abstract

Approximating the hereditary integrals by finite sums, a creep problem may be reduced to a succession of elasticity problems with initial strains. It is shown how the well-known general relationship between initial strains and equivalent loads may be applied to a composite beam on statically indeterminate supports. A highly accurate numerical method for memory-type creep problems is demonstrated and its convergence studied by means of examples.
