Abstract

Titanium foam is considering an important competitive in bio-system applications, this is due to its compatibility as well as fascination. Getting good sufficient data about fracture and mechanical properties are needed demand for scientific and Engineering works in the field of biomaterial and bio-system. Fracture toughness is measured numerically using J-integral finite element method based on crushable foam model. Three-point single notch bending specimen is used for the foam of 62.5 %, and 65 % porosity to measured surface release energy G_IC . this test is considered a stander test for linear material. it is found to be (2.3), and (1.36) kJ/m², for 62.5% and 65 % porosity respectively. this is usually used in human implants. The measured G_IC is acceptable compared with that experimentally measured in other published paper.
