This paper examines the high accuracy of the crack propagation analyses by using the Finite Cover Method(FCM). FCM was employed to simulate the crack propagation in elastic-plastic materials, and enables arbitrary crack generation and propagation. The linear triangular element is using by the conventional finite cover method. A high-order element has high accuracy of the stress, but it includes the instability, so this paper applied P1-isoP2 element to FCM.
