The n-value determines the allowable biaxial stretch within the stamping as defined by the forming limit curve (FLC). The traditional n-value measurements over the strain range of 10% – 20% would show no difference between the DP 350/600 and HSLA 350/450 steels in Figure 2. WebExperimental studies show that the value of a2' relative to a3' and a1 ' has an influence on the shear strength. Several common states of stress are shown in Figure 12-1. In the initial state (a), a' is the effec-tive overburden pressure, a' = K 0 a ' is the radial or lateral pressure, and K. is the coefficient of earth pressure at rest. resorts kemah tx
