Finite Element Analysis (FEA)
Finite element analysis (FEA) is a tool used to predict the performance of systems and components prior to manufacture. Whitefield Plastics offers linear and nonlinear FEA elastomer analysis to verify calculations and identify weaknesses prior to manufacture and physical testing. Analysis of urethanes is often nonlinear. Each unique urethane chemistry may exhibit a wide variety of physical properties even when comparable urethanes have similar chemistry. Often sensory observations cannot distinguish differences, while a combination of laboratory testing of engineering properties and FEA can accurately depict performance.
FEA is a common tool that was not reliably available for industry use until recently for nonlinear elastomers. Computing capacity and sophisticated programs are capable of providing accurate results that can be verified with physical testing.
At Whitefield Plastics, FEA is used to validate performance prior to manufacture, as well as confirmation of physical testing. FEA software is sophisticated and requires competent and qualified personnel to produce true component performance behavior. Analysis mesh style, paired with unique material properties and component geometry, are critical to predicting the physical performance of engineered solutions. Whitefield Plastics partners with third party FEA experts to ensure accurate modeling performance results.
