    How to use the Ogden model to plug in strain and get forces and vice versa

    Hello I have the stress/strain data for a rubber nonlinear material. If I use the Ogden model how am I going to use it to get the forces by applying strain values or vice versa? Thanks

    Displacement Error in Mechanic using Workbench

    Hello I placed a Displacement in the Static Structural under the Mesh edit in the Mechanical mode. I use tabular data to define the displacement but when I press Solve I get the error "You need at least one structural load to proceed with the solution". What is this error? Please help.

    How do I import tabular data from excel to ANSYS related to the geometry of a mesh?

    The excel data is the X,Y of a material deformed. In ANSYS the same material should be created in its original shape and dimensions. How do I apply the deformation to the original shape in ANSYS, when this deformation info should come from excel data?

    Inverse Engineering Force Estimation

    Hi I have a rubber hyperelastic material that I need to estimate the forces that cause its deformation when imaged on ultrasound images. I know there is a way to do it in ANSYS, by applying an ogden 1st order model and import the stress-strain experimental data I got from testing the material...

    Ultrasound standoff deformation validation test

    Roughly, what I want to find are the specificity and sensitivity criteria of the pin images, so I can estimate the accuracy of the standoff deformation

    Ultrasound standoff deformation validation test

    No, its not about calibration. The pin is not in the air. It is on the table. Above the pin is the standoff material which is plastic (polymer). Can you please answer now to my question? It is a polymer and rubber material as well.

    Ultrasound standoff deformation validation test

    Hello I am using a polyvinylchloride standoff for encapsulating the ultrasound probe while scanning. In order, to measure its accuracy on deformation related to specific forces, I need to do a validation test to assess its accuracy in deformation under known volume. In that essence, I am...
