in this paper, three-dimensional modeling of the fatigue crack growth profiles was performed in a simple riveted lap joint. simulation results showed that mode i was dominated on the one side of the plates and the crack straightly grew on this side, while the other side of the plates was in a mixed-mode condition and the crack propagation path was not straight on this side. afterward, the fract...

Prior detailed microscopic observations have revealed the essential mechanisms of damage in through-thickness reinforcing tows when a delamination crack passes. As expected, the damage sequence depends quite strongly on whether the crack is loaded in Mode I or Mode II and, if loading is mixed mode, the order of loading. Here, micromechanical models are presented that show how geometry and const...

Additive manufacturing (AM) is a topical field today and has received the attention of many researchers. However, further research needed to overcome challenges facing AM, especially in mixed-mode fracture. The results presented this paper are framing experimental data obtained for I/II fracture properties laser sintered polyamide. experiment was carried out on Semi-Circular Bend (SCB) specimen...
