Fracture Simulation: Advanced constitutive Equation for Materials behavior in special loading condition
In materials science, fracture toughness refers to the ability of a material containing a crack to resist fracture. Specifically, fracture toughness testing characterizes resistance to fracture in a neutral environment with a sharp crack, and is one of the most important properties of any material for virtually all design applications.
Finite Element (FEA) Fracture simulation is used in design and fabrication to understand and prevent brittle fracture. It can also be used to determine the useful life of a material under different conditions, including fatigue, corrosion and elevated temperatures.
