An illustration of plastic creep. (a) The plastic flow (creep) test: at a constant (high) temperature, the tensile stress is ramped and then kept constant. The strain continues to increase at a variable rate depending on the system. (b) An illustration of the rate of nonlinear plastic creep in the xLCE network depending on the level of constant stress kept. Such a test informs about the conditions and the time required to “program” the uniaxial alignment in xLCEs.
