Structural, Dynamic and Thermal Analysis
Assystem offers a comprehensive range of analysis services ranging from simple iterative solutions in support of the conceptual design process to the modelling of complex assemblies and structures. Our structure allows the formation of integrated teams to solve the most demanding of problems.
Assystem maintains a world-class capability in the field of Finite Element Analysis (FEA) through its investment in both training and software, and the accumulation of over 20 years experience in its use. General purpose codes such as Nastran, Abaqus and ANSYS are regularly utilised, whilst specialised packages such as SC03 are employed in more specific fields.
Structural Analysis
The range of structural analysis scenarios which can be modelled is virtually limitless. From the loading of simple structures to the consideration of complex non-linear events such as impact and collapse Assystem has the capability to assess the design of a structure, determine its suitability, and if necessary optimise it for the task it is to perform.
Tasks frequently undertaken include the qualification of new designs, fatigue life assessment and life extension of in-service components, checking of inherited analyses, failure investigation and weight reduction.
Dynamic Analysis
The techniques employed at Assystem allow for reliable interchange between structural and dynamic analyses. The scope of the work performed can range from simple assessment of the normal frequencies of a system, and optimising these to avoid resonant effects, to full forced response analyses in which the behaviour of a structure due to a dynamic load is determined.
Thermal Analysis
Assystem has extensive experience in the modelling of thermal processes in the high mass flow, high temperature environment present within a gas turbine and within high integrity nuclear pressure equipment. The complexity of the model is dictated by the nature of the problem, but can range from simple 2-D steady state models to the transient response of complex 3-D geometries.
