    Interlaminar Shear Stress between Composite Layers

    Can someone help me with looking at the interlaminar shear stresses between the layers of a composite in ANSYS. For now I am working with a single element model that I have used for data verification. The model has 40 layers of the same material at various orientations. Any help would be...

    Meshing w/ ANSYS (Classic and Workbench)

    I am trying to mesh a simple cylindrical pressure vessel with flat ends. I would like to have all hex elements of type SOLID186. Is there a way that I can force Workbench to mesh the cylinder with all hex elements? I am wanting to eventually incorporate composite layers in the model. Is...

    Applying thermal gradient in ANSYS Workbench

    Yes, I am just wanting to set the reference temperature to zero while the entire body is at a constant 700 degrees F, therefore creating a delta_t = 700. Thanks.

    Applying thermal gradient in ANSYS Workbench

    I have created a simple one-element model in ANSYS classic to compare to some theoretical results I have calculated. I have tried creating the same model in ANSYS Workbench, but I am having trouble getting the thermal gradient to work. The model I am working with has 40 composite layers of...

    ESAComp

    Does anyone know the advantages to having ESAComp to model composites as an add-on to ANSYS? I was just trying to figure out what the advantages/disadvantages were. Thanks.

    ANSYS Composite Layer Output Question

    I have modeled a basic 1-element model with pressures on the edges and a thermal gradient. There are 40 layers of the same material but at various fiber orientations. I was just curious if there is a method I can use to get the output such as sigma_x for each layer without having to change...

    Modal & Harmonic Analysis w/ ANSYS

    I am trying to learn the basics of modal and harmonic analysis. I have been looking over an example in a textbook I have, Finite Element Procedures by Klaus-Jurgen Bathe. It is Example 9.14 on page 818. I have tried running the problem in ANSYS, but I cannot get the values that are in the...

    Composite Pressure Vessel modeling in ANSYS

    Has anyone modeled a composite pressure vessel in ANSYS or in Workbench? Thanks.

    ANSYS Rayleigh Damping, ALPHA & BETA

    It is not a basic static structural analysis. I am trying to apply a concentrated end load to the beam that has a sinusoidal trend. The P(t) load curve is modeled with the function 4*sin(omega*t). I am new to ANSYS so I am not sure exactly how to apply this type of load. Do I use a harmonic...

    ANSYS Rayleigh Damping, ALPHA & BETA

    I am trying to run a basic model in ANSYS of a cantilever beam. What does ANSYS default the values of ALPHA and BETA to if they are not input into the program?
