摘要：
This paper refers to a certain class of hypoelastic materials for which work depends on the stress history. Using elements of the bifurcation theory, it analysed the modification of a material behaviour at small variations of constitutive constants. It is showed that, if the mean stress is greater than its bifurcated value, the material is stable, but when it reaches its bifurcated value, the material becomes unstable.
