Instability will occur when F1 = F2 equals zero. 9) dσ1 /σ1 = −d A1 /A1 = dε1 . 5. Effect of the inhomogeneity factor, f, on the limit strain, ε∗b , outside of the neck. 25 was assumed. 6. Effects of f and n on the uniform elongation, ε∗b . 11) ε¯ = 2ε1 = 2ε2 = −ε3 . 4. 7. State of balanced biaxial tension. 14) at instability. Note that this is twice the instability strain for uniaxial tension. 8 is a free-body diagram of half of a pressurized thin-wall spherical pressure vessel. 8. Free-body diagram of half of a pressurized thin-wall spherical pressure vessel.

What would the load be on an identical tensile specimen when the elongation is 20%?

5) The two regions, a and b, must support the same force so Fa = Fb , or A a σa = A b σb . 3. Stepped tensile specimen. 3. 4. Strains induced by various inhomogeneity factors. 05 Aa0 exp(−εa )K εan = Ab0 exp(−εb )K εbn . 7 simplifies to f exp(−εa )εan = exp(−εb )εbn . 8 can be solved numerically to give εb as a function of εa . 25. 25 where necking occurs. This implies that the maximum strain outside the neck equals n if f = 1. However if f < 1, εb lags behind εa and saturates at ε∗ which may be considerably less than n.
