Nonlinear Analysis

In addition to linear finite element analysis, DJH also has expertise in complex nonlinear analysis. Whether dealing with material nonlinearity such as an O-ring seal as in the example shown, or a combination of geometric and material nonlinearity as produced when simulating a Roll Over Protection System (ROPS) analysis for mobile equipment, DJHEC has the experience to produce accurate results in a shortened time frame with the aid of the HPC cluster. Comparison of ROPS FEA results has shown push distances to meet energy and force goals within 2 mm of recorded physical test data. The knowledge gained from past projects will be highly leveraged to provide guidance for you finite element analysis needs and ensure the accuracy of the output.
