Finite Element Analysis (FEA)

Finite Element Analysis is an extremely powerful tool that can be used in the assessment of operating equipment, components and structures. FEC select the most appropriate analysis technique, and software, to solve the problem at hand. From simple beam element structures through to dynamic explicit damage and fracture modelling, FEC have the experience to get the job done. FEC complete all FEA in accordance with industry best practice and provide comprehensive reports to fully document our methods and provide transparency for our clients.


FEA is used where conventional design by rule or fundamental calculations do not provide sufficient detail or become to cumbersome to complete the task at hand. So for complicated structures, highly complex loadings, transient modelling and combinations of the above, FEA makes sense. All of our engineers use FEA on a daily basis as part of performing design tasks, resulting in very high software proficiency. The collective FEA experience within FEC results in a highly efficient design process and ultimately a better outcome for our clients in a shorter amount of time.

FEA sees application in the design of pressure equipment, structures and machine components. Where the application of FEA is derived from a Standard (e.g. AS1210 or ASME VIII Division 2), those techniques are comprehensively applied to ensure all protections with the code are satisfied.
