摘要：

The progress of "c-axis tension" twinning in magnesium is represented in an analytical framework and this is used as a basis for predicting the flow stress. The difference in the stress-strain curves between tension and compression can thus be modelled with a change to a parameter that reflects the fraction of grains that undergo twinning.
