WebThis paper presents a nonassociated bounding-surface model by incorporating a fractional-order plastic-flow rule that is obtained by performing fractional-order derivatives on the bounding surface. It is found that the flow direction no longer necessarily coincides with the loading direction, even if the same potential and loading surfaces are used. Web1 de mar. de 1984 · The classical theory of plastic flow of metals assumes that any pressure dependence of yielding is associated with irreversible dilatation through the normality flow rule. Experimental results presented here on iron-based materials and on aluminum show that although the flow stress is a linear function of pressure, the plastic …
