The evolution of advancing computing technology has encouraged the use of finite element analysis to require constitutive models. mostly adopted extensive experimental datasets. Nevertheless. fewer material properties are required within the bilinear traction-separation relationship incorporated with the XFEM technique and require fewer computation efforts due to the energetic approac... https://www.nacrack.com/top-save-Black-Icy-Flum-Pebble-X-limited-save/
