WebThe Fracture Mechanics calculator allows for fracture analysis of a cracked part. The methods used include Linear Elastic Fracture Mechanics (LEFM), the Failure Assessment Diagram (FAD), and residual strength analysis. … In probability theory and statistics, a shape parameter (also known as form parameter) is a kind of numerical parameter of a parametric family of probability distributions that is neither a location parameter nor a scale parameter (nor a function of these, such as a rate parameter). Such a parameter must affect the shape of a distribution rather than simply shifting it (as a location parameter do…
