  • Advanced Light Weight Weapons Integration Platform (ALWiP) Structural Finite Element Analysis

    The ALWiP is a weapons mount platform that enables the weaponization of commercial helicopters for use in tactical aerial defense situations. The image above shows the ALWiP mounted on a BELL 407 helicopter in a configuration that allows for the use of Hellfire missiles and M134 Miniguns.

  • Reconstruction of Tullio's Adam

    On November 10, 2014, The Metropolitan Museum of Art unveiled a reconstructed statue of Adam, created by 15th-century Renaissance sculptor Tullio Lombardo. In 2002, the pedestal on which the statue was displayed collapsed and Adam fell to the floor, breaking into 28 large pieces and hundreds of small fragments. What followed was a twelve-year effort that has in many ways changed the world of monumental stone sculpture conservation.

  • Accurate FEA of Engineering Plastics - About MatWeb

    This presentation includes an overview of the use of MatWeb.com to find material data. It was given by Barbara Hudock of MatWeb at CAE Associates' Accurate FEA of Engineering Plastics Seminar, held on October 14, 2014 in Tarrytown, NY.

  • Accurate FEA of Engineering Plastics - Importance of Fiber Orientation

    This presentation was given by James Kosloski at CAE Associates' Accurate FEA of Engineering Plastics Seminar, held on October 14, 2014 in Tarrytown, NY.

    • When injection molding glass filled material, the fiber orientation will be a function of the molding process.
    • An injection molding code must be used to calculate the local fiber orientation.
    • The location of the mold gate will also effect the overall fiber orientation.

  • Accurate FEA of Engineering Plastics - Time-Dependent Response of Plastics

    Case Study: Time-Dependent Response of Plastics

    This presentation was given by Dr. Mike Bak at CAE Associates' Accurate FEA of Engineering Plastics Seminar, held on October 14, 2014 in Tarrytown, NY.

    The response of a threaded plastic cap used to seal a water spigot is investigated.

    • Cap is threaded onto a pipe, compressing the washer to create a watertight seal.
    • Loading consists of the axial preload and internal water pressure.
    • Structural response over a time of 2 years is predicted.
    • Room temperature.

  • Accurate FEA of Engineering Plastics - Strain Rate Effect in Falling Dart Simulation

    Case Study: Strain Rate Effect in Falling Dart Simulation

    This presentation was given by Steven Hale at CAE Associates' Accurate FEA of Engineering Plastics Seminar, held on October 14, 2014 in Tarrytown, NY.

    A model of a falling dart test was developed in ANSYS Workbench/LS-Dyna to demonstrate procedures for including strain-rate sensitivity in plastics and to show the importance of including this sensitivity when plastic parts are subjected to dynamic loads.

  • Accurate FEA of Engineering Plastics - Plastic Part Analysis Demonstration

    This demonstration showing how to analyze plastic parts using finite element analysis was given by Patrick Cunningham at CAE Associates' Accurate FEA of Engineering Plastics seminar, held on October 14, 2014 in Tarrytown, NY. 

    The presentation used in this demo is available for download, above.

  • Accurate FEA of Engineering Plastics - Keynote

    This presentation is the Keynote Address given CAE Associates' Accurate FEA of Engineering Plastics seminar, held on October 14, 2014 in Tarrytown, NY.

    Keynote speaker Hubert Lobo is President & Founder of DatapointLabs, with over 25 years experience understanding nonlinear material behavior and how it impacts product design, provides an introduction to the stress-strain characteristics of polymers: rubbery, ductile, and brittle plastics, along with special considerations required to successfully analyze each type.
