Required Material Properties and Curve Settings inputs

• Modulus of Elasticity (Ey), Engineering Yield Stress (sig_ys) and Engineering Ultimate Tensile Stress (sig_uts) must be specified at the temperature of interest.
• Derating factor (DF) is applied to the Yield Stress (sig_ys) and the Ultimate Tensile Stress (sig_uts) to obtain σys and σuts as defined and used in ASME [ASME 2013 VIII Div.2 / KD-231.4, ASME VIII div.3]
• Material Type must be selected from the drop list according to ASME [Table 3-D.1, ASME 2013 VIII Div.2 / Table KD-230.5, ASME VIII Div.3]
• Number points is the number of points used in ANSYS true stress true plastic strain curve.
• More points are placed where the slope is greater. Points are not equally spaced.
• Curve Start Point is the first point of the ANSYS true stress true plastic strain curve.
• The input required to define ANSYS multilinear hardening is the true stress – true plastic strain data points, starting at the point where true plastic strain is zero.
• The true stress – true total strain curve prescribed by ASME is a smooth curve, transitioning from the elastic to the inelastic range.
• Data points may be included by the user below the minimum yield stress.
