Prediction of Crack Propagation of Nano-Crystalline Coating Material Prepared from (SAM2X5): Experimentally and Numerically

The fracture and crack growth of materials can be practically conveniently predicted through numerical analysis linear elastics mechanics. On this basis, the current study aims to present experimental work supported by a technique for mimicking propagation Version 5.6 COMSOL Multiphysics (version 5.6), used simulation coating made from Fe-based amorphous material with thickness 300 µm. paper shows effects mixed-mode loading on cohesive zone parameters attained load-crack mouth opening displacement (CMOD) curves. microstructure dominates fracture, which in mode I is altered all-transgranular cleavage nearly all-intergranular structure II. Two common criteria failure are linked results: Maximum energy release rate criterion (Maximum G) maximum tensile stress S). However, distinguishing between two impossible large scatter data. intensity factor basis the. leading parameter facilitated singular element should estimated accuracy. With aim comparing each illustrating schemes’ robustness, number examples presented. It concluded that G S were successful accurate predicting prepared mild steel.
