The purpose of this project is to study the damage in composite materials fiber (fiber composite material) and predict the distribution of cracks in composite materials. By the method of finite element program, ABAQUSHashin Criteria which material study and test. The composite materials reinforced with glass fiber. By the test pattern is used as the test tensile strength (Tensile Stress).No damage model. No material damage in parallel to the fiber but are damaged in the direction perpendicular to the fibers. And know that the material damage will occur at the hole in the middle of the target!In the study of damage in composite materials fiber. There is only one layer with the arrangement direction 0 degrees.
