Simplified FE Modeling of Rolling Tires for the Simulation of Dynamic Forces at Hub Level

Being the support of the vehicle and providing forces necessary to control it, pneumatic tires are one of the most important components. Nevertheless, they are probably the most challenging components that have to be modeled due to both their complicated composition and the materials used in their manufacturing process. 

A Novel Methodology for Optimization of Product Properties and Production Costs in Fabrication of Aluminum Alloys

Manufacturers of aluminum alloys are faced with the increasing demand for products showing a consistent, robust and well defined property profile. This calls for a smart balance of opposing objectives capable of considering product properties and production costs along the process chain.

Composite Material Multi-Objective Optimization Using Ansa, mETA and modeFRONTIER

modeFRONTIER workflow automation and optimization capabilities enabled Formula 1 car front wing engineers to integrate with ANSA and mETA software and reduce the weight by 27.4% and the angle of attack by 2.5%, thereby significantly improving the drag coefficient.

Material Modelling at Volvo Cars, Mapturing Set of Stress-strain Curves for Efficient Reuse

Capturing data on variation in material quality and the correlations in material property is key to predict material failures and allow for model reuse. Material properties of the rear components of a Volvo car are analyzed from a safety perspective, to improve the energy absorption capability of the bumper and prevent components’ replacement.

Development and optimization of hydroxyapatite-ß-TCP functionally gradated biomaterial

In this work a method of optimization of mechanical behaviour of an FGM biomaterial coating or scaffold composed of HAP and beta-tricalcium phosphate (ß-TCP) is considered. For coating on titanium-based substrates which have anatase (TiO2) top layer, thermodynamic equilibrium was analysed and the “safe” compositional path was found to ensure preservation of original ceramic phases during processing. 

Calibration and validation of metamodels for hydroforming applications

This work focuses on the HydroForming (HF) process with the determination of the optimal working conditions through the adoption of an optimization procedure based on a numerical approach. The component chosen for the study is a component made by the AA 6061-T6. 

A CAE based procedure to predict the low velocity impact response of a composite CAI specimen

In this case, modeFRONTIER was coupled with an LS-DYNA FE model in order to simulate the impact low velocity impact on composite plate.

Metodologia de Analise de Implante Bioreabsorvivel Aplicado em Coluna Lombar Utilizando Modelagem por Elementos Finitos e Curva de Degradacao

Bioresorbable materials, consisting mainly of polymers, have as main components, lactic acid and bioengineering studies, which is the bioresorption process, i.e., the braking of polymer by hydrolysis into lactic acid and glycolic acid. These monomers are eliminated through body natural cycle called Krebs cycle. 

Design Optimization of Layered Composite Structures

Nowadays optimization problems quickly become overwhelming in terms of designs material selection for each layer, number of layers, layer orientations, stacking sequence and there is growing possibilities to use solid laminate, sandwich and stiffened structures. The advantages of expensive composite materials can be utilized only with the use of appropriate design and analysis methods.
