This is the first in a series of two papers generated from a study on probabilistic meshless analysis of cracks. In this paper (Part I), a Galerkin-based meshless method is presented for predicting first-order derivatives of stress-intensity factors with respect to the crack size in a linear-elastic structure containing a single crack. The method involves meshless discretization of cracked stru...

Mode-I crack propagation in quasi-brittle material such as rock and concrete is studied by a new numerical method, lattice cellular automata. Cellular automaton method is an efficient method that simulates the process of self-organization of the complex system by constructing some simple local rules. It is of the advantage of localization and parallelization. Lattice model can transform a compl...

Asymmetric Single Edge Notched Bend (ASENB) specimen which is exposed to asymmetric 3-point bending used estimate the mixed-mode fracture (I/II) in epoxy. The mode I and II combination stress intensity factors (SIF) were calculated for various locations of loading points different crack lengths using finite element analysis tool ANSYS. By selecting suitable support positions with point mixities...

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...
