    I need an extruded AL material suggestion

    Folks, I am working on an application like a big drawer slide. The slides are intended to be aluminum with steel balls running directly on them. Can anyone suggest an aluminum which would maximize the longevity of the slides and the contact stress issues. In addition this may be subjected to...

    Help with automotive static load cases

    I have recently hired a new stress analyst. His first task was to evaluate an UCA. We have ADAMS static loads (typical DELPHI static loads like 3g 3g, 6g one side, braking, lateral ...). I did it myself as an inertial relief problem and created 11 load cases, one for each static load. The...

    Failure criteria for FEA of glass

    I am trying to predict failure of a glass panel subjected to varoius loads. My FE model consists of solid elements. My question is what do I use for a stress criteria which will predict failure. The model will be used for multiple load cases. Thank you. Jim

    I need an estimate for the polar moment of inertia

    Folks, I need to estimate the pitch moment of inertia of a vehicle for Vehicle Sim. I have the corner weights as well as track and wheelbase. My first thought was to treat the vehicle as a dumbell with two different size masses. The pitch moment would be the sum of the mr2 with r being the...
