Square container at 0.7MPa
Thread Content
Square container, with dimensions of 300mm*300mm, and an extreme internal pressure of 0.7MPa. Given that the tensile strength of the material is 120 MPa (not that of stainless steel), what wall thickness would be appropriate? How should one estimate the strength, or where can it be found? This is my first time dealing with such issues; please give me some guidance.
It is recommended that the poster consult Appendix D of the GB150 standard and related technical books……
Thank you, I really can’t understand it, sigh.
In accordance with Article D3.1 of the appendix to GB150, first assume the wall thickness, and then calculate the membrane stress and bending stress at points N and Q of the side plates respectively, so as to meet the stress verification requirements. The wall thickness can then be determined.
