Contact penetration

impauto

Dear guys,

I am new in hyperwork .I have problem regarding contact penetration.Actually it has three component first cylinder with 39.8 dia with SS material , O ring having internal dia 30.1and thicknes 5.1 with rubber properties and metal tube with OD 31.8 again SS material.Actually in Preload condition how much O ring compressed or contact area when we assembly the cylinder with tube.After that a 3 bar pressure is applied from Max contact pressure will be there. I already worked on given below hm file but can't get result.For better understanding I just also share image file.Thanks and regards in advance.Its very urgent.

Hi Nikkss,

I see that the material used for rubber is becoming unstable even at very low strains.

How did you get the Mooney Coefficients? Do you have a material stress-strain curve which you could share

Thanks
