Routine FEA Analysis
Be it 3D or 2D idealisation, FEA can be used for rapid analysis of complex systems. In many cases a properly considered linear model will give good indications of a structures performance for sizing purposes before starting more complex analysis.
Many small FEA companies will provide minimal or weakly justified analysis reports that hide modelling or assumption errors. With RTJ Consultants you can expect detailed justification reports for all work we do. Our consultants have been drawn from industries with high regulatory and quality requirements. Quality is built into our mindsets from decades of experience.
Loads Models
Do you have a complex assembly with many load cases. RTF Consultants can build you a loads model, perform load case down selection and then link the output to either traditional analysis or create detailed sub models for assessment of details. This is workflow is fast turn and our consultants have decades of experience of best practice for both modelling and idealisation.
Meshing Services
Meshing is not just pressing a button. Building an effective mesh requires detailed knowledge of the fundamentals of FEA, the elements and the best practice methods of idealising components, joints and boundary conditions to ensure accurate simulations in the areas needed. RTF Consultants are industry experts at this.
Linear Static Analysis
Linear analysis is a rapid approach for most cases and is the bread and butter of FEA analysts. Generally, this is associated with small displacement theory however with good knowledge of structures and analysis methods even complex non-linear behaviours can be linearised. Even when it is necessary to carry out more complex non-linear analysis, these models are used as validation steps. RTF Consultants will never run non-linear analysis without verifying its behaviour with a robust series of linear checks.
Modal Analysis
By default, RTF Consultants perform modal analysis on all models we generate as it is perfect for assessing a model’s behaviours and connections are as expected. Often modal analysis can be used to ensure problematic frequencies are avoided as a precursor to frequency response analysis or as an input into traditional methods.
Buckling
Linear buckling analysis is a typical check for most load bearing structures. However, it should be noted that these are linear models and predict the onset of buckling. Buckling is not a final failure and if post-buckled residual strength or deflection analysis is required more complex analysis can be performed.
Thermal Analysis
Are you concerned about thermal effects? Do your scenarios involve radiation, convection or conduction? Linear / non-linear steady state and transient heat transfer methods can be easily performed. Not only can RTF Consultants implement the analysis, but they have a detailed understanding of temperature dependant material properties.
