The Case for Standardization
As managers are promoted or re-assigned and as experienced engineers retire or leave for other opportunities they take with them valuable assets of the corporation: experience and know-how forged from countless design changes and analyses.  These intellectual assets can be preserved and re-purposed with the CAE Handbook powered by StressCheck.

The proper application of numerical simulation procedures requires subject expertise and expertise in computational engineering that are not common or readily available.  However, it is possible to leverage both kinds of expertise through standardization of recurring analysis tasks just like handbooks and manuals have provided the expertise of specialists in applied mechanics to mechanical, aerospace, and structural engineers for decades.

The essential difference is that classical handbooks present results for parameterized problems solved by classical or empirical methods, whereas standardized CAE Handbook procedures rely on verified FEA solutions of parameterized models.  This allows standardization of models that are of much greater complexity and focus to be treated as entries in a parameterized electronic handbook with guaranteed reliability.

An example is a seemingly simple assembly or gears or components in a lap joint.  In both cases the geometry is simple.  In both cases the analysis (e.g. model formulation, contact/gap of components, non-linear material properties involving plasticity) can be more complicated than what the well-defined geometry would initially indicate.
In order to ensure proper use of standardized parametric models by engineers and designers who do not have expertise in computational engineering, it is necessary to incorporate rules and automated quality assurance measures.

An important advantage is that advanced parameterized models can be archived and shared by engineering groups at different geographic locations.  This ensures that consistent results are produced by tested and approved analysis procedures.

An example of this, showing standardized parametric models for protruding head, countersunk and blind fasteners, is shown in the figure below.  For further information please refer to ESRD’s Product Brief: SFAT - Single Fastener Analysis Tool.

The basic framework designed to support standardized simulation procedures is now being introduced into engineering practice.

Leverage and standardize your corporate expertise with StressCheck’s CAE Handbook.  The number of applications that can be inserted in the CAE Handbook has no upper bound.  The possibilities are endless.
