  • Boat Hull Multi-Paneled Window Stress Analysis

    A leading manufacturer of boating equipment had to meet strict deflection and stress requirements for a multi-panel boat hull window within very limited time constraints. CAE Associates was chosen for this project based on our experience and expertise for projects of this type, and on our commitment to produce the results within the narrow time frame allotted.

  • Bone Remodeling Predictions using ANSYS

    Stryker Orthopaedics, a global leader in the development, manufacture and sale of orthopaedic products and services, sought to develop customized finite element simulations to evaluate long term, bone-implant interaction by characterizing bone density changes in hip and knee replacement recipients over a period of years. CAE Associates incorporated a bone remodeling algorithm into ANSYS via the USERMAT material model user-subroutine.

  • Balloon Angioplasty Finite Element Analysis

    To better understand the effects of different angioplasty balloon compliances, a Finite Element Analysis (FEA) computer simulation was performed by CAE Associates, using commercially available nylon (semi-compliant) and PET composite (non-compliant) balloons.¹ The simulations demonstrate the effect of balloon compliance on vessel stress during angioplasty.

  • An Easy-to-Use Tool for Generating a Spoke Connection in ANSYS

    The process of creating the spoke connection can often be time consuming and the user may not be aware of which connections are valid for the analysis conditions. To address this need CAE Associates has developed an ANSYS macro that walks the user through the generation of the spoke connection.

  • ANSYS/LS-Dyna Analysis of a Valve Actuator for Stanley Bostitch

    Stanley Bostitch was designing a new valve actuator for their next generation of pneumatic power tools. CAE Associates was asked to develop the design tool, which would help them to improve valve timing without adversely affecting other critical design criteria.

  • ANSYS Workbench Plastic Cake Container Optimization

    Inline Plastics Corporation designs and manufactures plastic containers used to package food items. The manufacturing process starts with rolls of plastic that are fed into machines that form the final shape of the containers. The design goal was to optimize the cake container design with respect to material use and visibility, while maintaining sufficient structural stiffness to prevent buckling when the containers are stacked or when handled by consumers. Inline Plastics chose CAE Associates to help with this project based on our expertise in nonlinear structural analysis and optimization.

  • Multi-Part Projectile FSI Analysis

    CAE Associates was chosen to help develop the solution based on our long history of ballistics analysis, our expertise in explicit dynamics, and our experience in the use of the AUTODYN software. CAE Associates’ client was interested in developing a methodology for the explicit analysis of multi-part projectiles using the ANSYS AUTODYN software. Prior methods did not adequately capture the complex interactions and physics required for an accurate solution to this problem.

  • Parametric Modeling of an Otis Elevator Safety Brake

    Faced with a design challenge, Otis Elevator turned to CAE Associates. CAE Associates utilized the ANSYS general purpose finite element software to develop a parametric model of the safety design.
