If the limit internal pressure is calculated accurately, it is great significance to prevent accidents and reduce risk. There are many engineering materials that the tensile strength and tensile modulus are dierent. These dierences have a significant eect on the ultimate internal pressure. Previous studies have shown that only considering one aspect of the tension and compression strength and the modulus of tension and compression has a certain error with the actual situation. With consideration of t
