Jerzy, Thank you very much for the answer, I really appreciate:) Homutow

Hello Jerzy, Thanks for answer. The material I use seems not to follow the rules of 2/3. Tensile Ultimate is min 80 MPa and flexural ultimate min 180 MPa. I am wondering why the flexural strength is so important if tensile strength is usually used? As I wrote previously I am new in plastics:)

I am doing FE analysis of the plastic part (similar to Bakellite). I have two material properties: tensile strength and flexural strength. I am little confused which value to use as a criteria for the design (I use first principal stress)? Till now I have used flexural strength because stress...

Thanks desertfox for the answer.

I am calculating a design where plastic cover (material similar to Bakellite) is clamped with a bolt. I have calcualted the pressure under the bolt head and it was about three times the compressive stregth. I would like to ask if anybody had experience with too high contact stresses, what are...

Hi, Recently I got a task to perform thermal fatigue analysis of solder joints. Till now I had nothing to do with such objects. Does anybody perform such a task?? I can prepare the FEA model but there are many questions: - what would be the material model? - Is there any approach to calculate...
