State-bounded directional accumulation in post-liquefaction sand: A hypoplastic formulation for asymmetric cyclic deformation

Experiments on saturated sand show finite, bilateral post-liquefaction strain accumulation with a larger strain excursion on the triaxial-extension (TE) than on the triaxial-compression (TC) side, whereas existing constitutive treatments still struggle to reproduce this asymmetri...
