Finite Element Simulations
ANATECH, a Structural Integrity Associates company, and its principals have been in the forefront of finite element modeling and analysis for over 40 years. We have developed many finite element programs and methods ranging from specialty element formulations, to solution techniques, to advanced, mechanics-based material models. We have applied finite element modeling and analysis methods to hundreds of application projects to find engineering solutions.
A critical aspect of finite element modeling and analysis is the experience and expertise required to evaluate and convert the analytical results into useful and practical engineering information. Performing a complex and sometimes costly analysis is useless if the critical results cannot be extracted and transformed into relevant information that can be used to solve the basic problem under investigation.
In performing Finite Element (FE) modeling and analysis, it is important to always understand the purpose and objectives of the analysis. Two types of analyses are typically performed, design analysis and predictive analysis. The purpose of design analysis is to demonstrate that a structure meets its design requirements, that is, the forces and moments (stresses and strains) are less than allowable values defined by a design code. The purpose of a predictive analysis is to accurately predict the actual response of a structure to actual loadings, up to and beyond its design basis.
