This model deals with the stability of a plate with an edge crack that is subjected to a tensile load. To analyze the stability of exciting cracks, fracture mechanics can be utilized. A commonly used parameter in fracture mechanics, used to predict if a specific crack will cause the plate to fracture, is the so-called stress intensity factor KI. When this calculated value becomes equal to the critical fracture toughness of the material, KIc, (a material property) then fast, usually catastrophic fracture occurs. In this model, you determine the stress intensity factor KI using the so-called J-integral.

The solution of any problem is based on the numerical solution of partial differential equations by the finite element method. The range of tasks that can be modeled in the program is extremely wide. A set of special modules in the program covers almost all areas of application of partial differential equations. COMSOL Multiphysics (Femlab) is a simulation package that solves systems of nonlinear partial differential equations by the finite element method in one, two, and three dimensions. It allows you to solve problems in the field of electromagnetism, the theory of elasticity, the dynamics of liquids and gases and chemical gas dynamics. Femlab also makes it possible to solve the problem both in a mathematical formulation (in the form of a system of equations) and in a physical one (choice of a physical model, for example, a model of the diffusion process). Of course, in any case, the system of equations will be solved, and the only difference is the ability to use physical systems of units and physical terminology.

In the so-called physical mode of operation, it is also possible to use pre-defined equations for most phenomena that occur in science and technology, such as the transfer of heat and electricity, the theory of elasticity, diffusion, wave propagation and fluid flow.
