Effects of High Toughness and Welding Residual Stress for Unstable Fracture Prevention
Applied Sciences, 2020 Unstable fractures generally occur in brittle materials under low-temperature service conditions. Toughness and welding residual stress are the main factors that should be evaluated when defining a brittle crack propagation path. In this study, a rainbow

Investigation on the Applicability of Several Fracture Criteria to the Mixed Mode Brittle Fractures
Advances in Mechanical Engineering, 2013 Mixed mode brittle fractures are very common failure behavior for cracked brittle materials under loading, and therefore, the prediction of the mixed mode brittle fractures is significant.

Fracture mechanics of micro samples: Fundamental considerations
Materials & Design, 2018 In this review article we consider the crack growth resistance of micrometer and sub-micrometer sized samples from the fracture mechanics point of view. Standard fracture mechanics test procedures were developed for macro-scale samples, and reduction of ...

Graphical modeling and animation of brittle fracture [PDF]
Proceedings of the 26th annual conference on Computer graphics and interactive techniques - SIGGRAPH '99, 1999 In this paper, we augment existing techniques for simulating flexible objects to include models for crack initiation and propagation in three-dimensional volumes. By analyzing the stress tensors computed over a finite element model, the simulation determines where cracks should initiate and in what directions they should propagate.

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
