Popis: In this study, the aging and yielding properties of a lyotropic liquid crystal phase undergoing shear induced structures transition are uncovered. Once transformed, the studied material is shown to acquire all the macroscopic properties of the so‐called soft jammed systems. Based on the analysis of inertial coupling effects in creep measurements, it is shown that the long‐time behavior of the investigated system can be predicted by a simple evaluation of its elasticity at short times.
