Entropic Limit Analysis Applied to Radial Cavity Expansion Problems

Entropic Limit Analysis Applied to Radial Cavity Expansion Problems

Analytical solutions of limit analysis design for the simple problem of plane strain expansion of a cylindrical cavity are derived and generalized into entropic extremum principles that allow a fundamental assessment of coupled thermal/hydro/mechanical/chemical (THMC) material instabilities and thei...
