Factors influencing CRB test results
Factors influencing CRB test results
This contribution deals with simulation of fracture behaviour of specimens for CRB (cracked round bar) test. These specimens are used for accelerated testing of polymer materials’ performance for piping applications. The CRB test is one of the most effective methods of testing due to use of cyclic loading instead of more common static force. However, in some cases the CRB specimens’ fracture surfaces come out asymmetrical. With the use of FEM simulation of the crack propagation in CRB specimens, the influence of this asymmetry on the results of CRB test is investigated.
