Helpful Hints and Tips: Automated 3D Beta Factor Curve Sim App
Abstract: Computation of verified 3D beta factors based on SIF’s extracted from one or two offset hole corner cracks in a plate under tension and/or bending. A continuation of the Excel VBA driver “Helpful Hints and Tips: Excel VBA 3D Crack Driver Example“.
Originally developed for a training course at the 2019 ASIP conference in San Antonio, TX.

“The p-type element has been used to great advantage in the finite element system ESRD StressCheck®, . This software provides the engineer with the means to conduct solution verification in an extremely straightforward manner by simply increasing the degree of the element, monitoring convergence and using Richardson extrapolation reliably to estimate the error. This can be conducted automatically by the software thereby enabling the engineer to concentrate on the engineering rather than the simulation. StressCheck® has also been used to develop ESRD’s Handbook and Toolbox applications. The first of these provides engineers with a repository of parameterised standard problems of the type found in texts like Roark’s “Formulas for Stress and Strain”, . The second, Toolbox, is a tool that can be used to parameterise a company’s range of components for rapid and reliable analysis by non-expert analysis. Toolbox then is an exemplary of the way in which the democratisation of simulation can be applied.”
