    Uniaxial Strain Limit in Section VIII Div 2 Part 5

    Are the formulas correct in Table 5.7 in BPVC VIII Div 2 Part 5 (Uniaxial Strain Limit for Use in Multiaxial Strain Limit Calculations)? I have a stainless steel with a reported elongation at break of 35%. The uniaxial strain limit is calculated as 3*ln(1+E/100) = 94%, almost three times higher...

    Stress-strain curves following ASME VIII div 2 Annex 3-D

    Hi! I have made a stress-strain curve for 245SMO material (S31254), which has S_y = 310MPa and S_u = 670MPa according to ASME II part D. My material datasheet tells me that the elongation at failure is 35% (engineering strain). Now, using the formulas in AMSE VIII Annex 3-D, I calculate true...
