Experimental investigation on dynamic fracture toughness of offset crack material using caustic method

The dynamic fracture behavior of notched semi-circular bending(NSCB) subjected to hammer impact loading was studied by using caustics experimental method.The results show that the shear stress at the crack tip increased with the offset distance increased, and correspondingly, the crack changed from...
