Structural Integrity of Laminates: Fracture Modes I, II, and I/II Under Various Loads

In many engineering applications, laminated structures are vulnerable to cracking under various loading scenarios. For structural integrity and design, it is essential to comprehend fracture behavior under different modes. The common fracture modes in laminates are mode I,mode II and mixed mode I/II. Cracks propagate in three major ways; mode I is perpendicular to the applied tensile stress, mode II is parallel to the applied shear stress, and mode I/II combines elements of the two modes. This lays the groundwork for investigating laminated constructions’ fracture behavior and mechanics under various loading scenarios.
