Why FEA?

Finite Element Analysis (FEA) based structural stress analysis is a valuable tool in the evaluation and optimisation of product designs for systems involving structural stress due to mechanical and thermal loading.
CAD models of the product are used to develop a computer model of the system, which is then subjected to expected load combinations. The resulting stress distribution and structural deformation may then be obtained and used to assess design safety as well as predict the expected fatigue life of the design. For systems involving dynamic loading, FEA may also be used to obtain the dynamic response of the structure.

Design guidelines and limits from relevant industry standards are used together with the FEA solutions to form an engineering judgement on the design sufficiency and identify any necessary modifications.

Using FEA as part of your product design process allows for the rapid and cost effective virtual testing and optimisation of your designs. This will reduce overall product development costs, improve design performance and also give your team greater insights into how your design is likely to respond to a range of operating conditions.

SDEA engineers are experienced in applying FEA to a range of industries and application areas.

 Pressure vessel FEA

Design by analysis is gradually overtaking the use of more traditional design by rules in the pressure vessel industry. More demanding designs in terms of reliability and safety together with costs of production are responsible for this push towards more advanced design techniques. Increasingly, many large customers also require their suppliers to obtain third party design assessment as a requirement.

HISC stress analysis

Structural stability is a major issue in wind turbines and other slender structures. Local buckling safety of towers under extreme wind loading conditions is complicated to assess due the high non linear nature of this failure mode. Minimization of tower´s mass may compromises the stiffness and strength levels of the structure especially under abnormal environmental conditions.

Fatigue assessment FEA

Fatigue assessment using FEA fracture mechanics

Engineering assessment of allowable crack sizes is an alternative to fatigue life strength calculations. Industry and standards´recommendations are slowly moving towards this kind of FEA methods. Stress intensity factors and maximum allowable flaw size for a set of given operational conditions is accurate predicted by SDEA using FEA enriched methods.

Structural stability is a major issue in wind turbines and other slender structures. Local buckling safety of towers under extreme wind loading conditions is complicated to assess due the high non linear nature of this failure mode.
