Dynamic stiffness of rubber bushing with static pre-load
Hello, I am interested to model a rubber bushing and to calculate its dynamic stiffness (frequency analysis). The bushing is pre-loaded, which means it could have large deformations. Any good advice on...

HI, You should set up a Prestressed Analysis – Frequency Domain . That probably requires the Structural Mechanics Module. One challenge in this type of problems is to select a material model that has a...

Hello, Thanks for your answer. I guess that one of the issue is to, firstly, make the pre-stress, using some hyperelastic material (Mooney-Rivlin), and secondly calculate the frequency response using a...

There is a pre-defined analysis type for this in COMSOL called “Prestressed Analysis – Frequency Domain”. Regarding switching materials between the two studies/steps it is possible and in some cases it...
