[題目]For plane-strain deformation(dε2 and σ3=0),sketch the von Mises yield
locus for the first quadrant in σ1-σ2 stress space.
(a)Indicate how dε1 and dε2 would appear according to normality.
(b)Determine the plastic work per unit volume as a function of principal
stresses and strain increments.
(c)Explain your answer in (b) with reference to the plot in (a).
我的解答:
(a)Indicate how dε1 and dε2 would appear according to normality.
解: dε2 and σ3=0
瓶頸: 要如何繪圖表示?
(b)Determine the plastic work per unit volume as a function of principal
stresses and strain increments.
解: dω=σ1dε1+σ2dε2+σ3dε3
∵dε2 and σ3 =0
∴dω = σ1dε1
(c)Explain your answer in (b) with reference to the plot in (a).
解: dω = Fx dx
瓶頸: 要如何繪圖表示呢? (寫寫自己的想法，方便大家為你解答)
以上瓶頸部份，麻煩版友們幫忙作解，謝謝!!
