摘要: Abstract A moving quenched soda-lime glass plate with an initial edge crack is modeled, applying the eXtended finite-element method (XFEM) in order to investigate stress field components and Von Mises around crack. The convective heat boundaries considered thermal formulation. Crank–Nicolson time integration scheme reformed adjusted a view accurately solving system of transient conduction matrix equations. In simulate whole stages problem formulation, MATLAB XFEM (MXFEM) codes are written employed. distribution contours plotted detail fields tip compared quantitatively. variations intensity factors (SIFs) during propagation obtained through calculation domain form interaction integral. verify procedure display ability developed results experimental outputs from literature.
