Abstract A simple (quadratic) mathematical model for predicting the deflection path of both non-tapered and continuously tapered cantilever beams loaded with a vertical end force is presented. It is based on the proposition that the path is a function of the ratio of the endpoints’ moments of inertia. The model is valid for both small and large (the tip makes a 70 degree angle with the horizontal) deflections. This was verified through physical testing, comparison to solution of the Bernoulli-Euler equation, and results obtained through nonlinear finite element analysis. Predicted endpoint deflections were found to be accurate within 1.8% of the actual deflection path for moment of inertia ratios varying from 1:1 to 1000:1.

Final Design

The combination of simulation and physical testing is powerful. In this case study Finite Element Analysis (FEA) and a 96 tonne load test were used to prove that the lifting points for a new semi-rigid inflatable rescue craft met their statutory requirements before full manufacture. The FEA was used to optimise the detailed design of the lifting points, without the need to test each different configuration, and the load test was used to prove the final design in practice, before full manufacture. The FEA showed that the bearing stresses in the Glass Reinforced Polymer (GRP) hull of the initial design were unacceptable and appropriate design changes were made from further analysis. However, to suitably risk manage the project a full load test was required to demonstrate that the revised lifting point details met their statutory requirements, before full manufacture of the new craft.

Elastic Strain Energy Density

Abstract The purpose of this paper is to provide a review of methods used to characterize the elastic behavior of rubber for use in Finite Element Analysis (FEA). A sample of elastic strain energy density functions used to characterize rubber is given, along with the tests required to characterize rubber according to these functions. The use of synthetic test data as an alternative to full physical testing is discussed, and highlighted by a case study. The paper closes with a discussion on potential errors associated with FEA of rubber components.

Vehicle Rollover

Two repeatable dynamic rollover performance testing systems have been demonstrated and reported upon. Here a review of each system is presented in which the general characteristics of each system are discussed. To assess how the results obtained from the two systems would compare, finite element models of rollover tests characterizing the two design approaches were utilized. The results from a published rollover test using one of the systems was utilized as a reference test. For each system, the vehicle rollover impacts were simulated under the same initial impact conditions. The results of the simulations were then compared. It was found that the simulations for both hardware systems produced results that were consistent with each other using state-of-the-art finite element analysis tools.

A comparative finite element analysis (FEA) model was developed to predict the relative stresses and strains in Zimmer NexGen®Trabecular Metal™ Tibial Cone components. The FEA predictions were compared to measurements obtained through physical testing. The model was validated for its ability to correctly rank the order of predicted strain in the components under applied load.

This paper presents the theory, experiment setups and solution implementation of Hyperelastic Material Models in Finite Element Analysis to provide the description of material behavior that matches the conditions the product sees in real life. This can be a complex matter because the real life scenario may have the product responding simultaneously to a multiplicity of conditions such as rate, temperature and the environment. Physical testing of elastomers for the purpose of fitting material models in finite element analysis requires experiments like uniaxial tension, biaxial tension, volumetric compression in multiple states of strain under carefully considered loading conditions.
