Hello,

Hi @reymart.laranjo 

 

Are you focusing only on the maximum result of 85000 MPa? 99% of the model is above the yield strength of the steel!

 

You are correct that something is wrong. Either the load is wrong (the applied pressure of 555 MPa = 80500 psi seems a little high!) or the design is wrong.

Hi @John_Holtz ,

I intended to use that 250t I converted it into pressure which is 555.55 MPA. And check if this type of design suits it. Just kindly ignore my design that's the type we wanted.

I just wanted to know if the 85k MPA is correct. or could somebody check my model if it's correct? or I have done something wrong?

 

krgds,
