| Abstract: | This paper established the scratch model of the cabin glass and obtained fracture toughness of face crack and threshold level of scratch propagation of MDYB -3glass,and established residual str ength specification and the method o f calculation for the scratch tolerance value,and gave th e scratch tolerance value of MDYB -3g lass that thickness is 9mm and provided some simple methods for disposing outfield scratch prob-lems. |
