Experimental study on fracture toughness K_(IIc) of concrete

Abstract
Experimental study on concrete fracture of mode Ⅱ has been carried out by using the specimens of double-edge notched mode Ⅱ.Experimental results show that initial crack angle is approximately 0° and the crack extends along the direction of ligament.It is observed that the concrete fragments with typical shear fracture exist on the fracture surface in the front of the crack tip.It is shown that a shear crack develops at the notch tip and crack...
