Elastic-plastic creep analysis of high temperature nuclear reactor components

Elastic-plastic-creep-large strain analysis at elevated temperature by the finite element method

“…In Ref. [14], a non-isotherma l elasti c-plastic-cree p computer program is developed for flat and curved , thick and thin shell elements of triangular and quadrilateral form . Subtle refi nements to the phenomenologi ca) theory have been discussed and their importance stressed by varions researchers .…”

“…In general , one can wri te F(S~~ a~~~, ~~~ T) = 0 (14) where E~'~ is the plasti c component of strain.…”
