The fracture resistance behaviors of the semicircular bending (SCB) PMMA specimens with different geometry are experimentally investigated. In order to evaluate the effect of orientation, location and right roll’s distance, a series of SCB experiments are performed on the PMMA specimens with different notch angle and location on the universal mechanical testing machine. Finally, the variation of the fracture load and the load vs. displacement relation are displayed and evaluated respectively.
