Calculation of composite panel strength
Thread Content
Hello everyone! I have a question: When calculating the strength of composite panels, how is P&q; B(q(L#h) determined? For example, Q345R 6MM + S30408 2MM: the design temperature for the inner cylinder is -20 degrees, while the design temperature for the jacket is -50 degrees. The design pressure for the inner cylinder is 0.66, and the design pressure for the jacket is 0.33. Should Q345 be used for calculating the parameters of the inner cylinder?

The materials used in this example are confusing; with a jacket design temperature of -50, how can the inner tube be made of Q345R?
Besides, for a substrate of 6 mm, is it necessary to use a stainless steel composite panel? Just using regular stainless steel would suffice.
The strength calculation of composite plates can refer to clause 4.4.3 on allowable stress of composite plates in GB/T150-2011.1.
