Investigation Of Mode I-Ii-Iii Fracture Of Brittle Spheres With A 60° Internal Crack Using 3d-Ilc, Hai-Jun Wang, Shu-Yang Yu, Zi-Xuan Tang, Lei Tang, Ran Ren, Jin Xu

Rock and Soil Mechanics

As one of the perfect geometries in nature, sphere is common in daily and industrial life. The mechanical properties of sphere are of great significance to engineering safety and numerical simulation. Internal cracks or defects are inherent properties of materials and have an important influence on the mechanical properties of materials. However, the internal crack of the sphere is not considered in the current research due to the limit of technology. Thus, understanding of the propagation of internal cracks of brittle spheres is limited. In our study, internal cracks were created in glass sphere samples by 3D-ILC (3D-internal laser-engraved crack). …
