Numerical simulation of crack propagation from microcracking to fracture

Schorn, H. / Rode, U.

AbstractBy numerical simulation, damage processes of quasi-brittle composites can be studied. The Bochum Method allows the calculation of all states of cracked material structure during the loading process from microcracking to fracture. Using this method a damage process of tensile loaded material was found which is not identical with assumptions used for determining the GF value of fracture energy. Separating energy in (micro)crack formation from (macro) crack propagation, the authors propose a procedure to evaluate the GF value from tensile or bending tests.
