Solve your challenging engineering problems by partnering with Re:Test

Nowadays, a lot of CAD packages (e.g. Solidworks) include Computer Aided Engineering (CAE) software. These simulation packages are optimized for ease of use, so that engineering analysis can be accessible to deigners with little or no CAE experience. These tools work well for a lot of analysis scenarios, where accuracy is less important. However, in cases where the product:

• Has to be highly optimized to meet challenging strength, weight or cost reduction goals
• Is subject to a complex operating environment
• Has a complex structure or interactions

These packages cannot be trusted, and more sophisticated tools become necessary.

While there are a lot of companies that can provide CAE services, Re:Test is the only company that has in-depth knowledge and experience with every step in the analysis and product development chain. Over the last 40 years, our consultat Nigel Linden has had practical experience in the following areas:

• Static and Dynamic Implicit and Explicit Finite Element Analysis (FEA)
• Multi-body Dynamics (MBD) including FTire and flexible bodies
• Fatigue Analysis
• Computational Fluid Dynamics (CFD)
• Co-simulation
• Multi-physics modeling
• Laboratory-based testing and simulation
• A thorough technical and practical understanding of fatigue, durability, multi-body dynamics and vibration
• Characterization of materials and components to calibrate inputs, interactions and constraints
• Understanding the effects of boundary conditions from years of practical experience in modeling and physical testing
• Manually coding and buiding analytical models beginning in the early 1980s when computers filled a room
• Deep understanding of the limits of instrumentation and digital signal processing
• Correlation of model results through verification tests

Re:Test is able to provide a broad range of advanced analysis services for your more challenging engineering problems. Our unique understanding of the interaction between fatigue and dynamics coupled with our extensive suite of CAE products with multi-core processing, means that we can perform fatigue analysis on non-linear static and dynamic implicit and explicit simulations, and on multi-body dynamics with flexible bodies. We can also use cosimulation to model highly complex non-linear multi-physics interactions. Not only that, but if there is information that is required to improve model accuracy, we have the laboratory experience to specify the tests and data collection that are required for the calibration of input loads, materials, interactions and constraints. Once modeling is complete, we are uniquely able to design a testing and validation program to give you the confidence that the solutions we derive will enhance your product’s performance in the real world. Our solutions are practical, cost effective, and have the accuracy necessary to give you the answers you need. 

Re:Test uses SIMULIA Abaqus/CAE Extended with iSight, TOSCA and Fe-Safe. These packages allow us to perform non-linear implicit and explicit FEA analysis using the most advanced solver in the industry. TOSCA is an award-winning design optimizer, and Fe-Safe is uniquely able to perform durability analysis on rubber.

This is complemented by durability analysis from the full nCode Design Life (Prenscia Access) package for data processing and analysis, fatigue analysis of spot and seam welds (including Whole Life), vibration, Thermo-Mechanical-Fatigue (TMF) and composites. We are also able to couple in the Accelerated Testing package to develop lab-based durability tests.

For Multi Body Dynamics analysis we have the full suite of MSC Adams, including flexible body analysis and FTire for simulating automotive tire dynamics

We use Altair's hyperworks for pre and post processing

For non-linear modeling of hyper-elastic materials we also have MCalibrate and PolyUMod from PolymerFEM .

The video above was produced by Hawkridge Systems, the largest distributor of Simulia products in the USA. They decided to feature the work we do with their software because of the interesting applications we get involved in.
