Using a thermodynamic model based on the generalized Landau free-energy density expansion, we investigate the influence of hydrostatic pressure on the spontaneous polarization and tilt angle of ferroelectric chiral smectic C (Sm C*) phase near the Sm A–Sm C* transition in a ferroelectric mesogen DOBAMBC. It is shown that the pressure dependence of the tilt angle, spontaneous polarization and Sm A–Sm C* transition temperature (Tc) can be described in terms of four pressure-dependent Landau coefficients: two achiral coefficients a and b and two chiral coefficients Λ and d. The pressure dependence of the parameter a is due to the pressure-dependent Tc. With the increasing pressure, the stability of the Sm C* phase decreases. A close agreement between theory and experiment is found.

AbstractThe shock-wave properties of ED-10 epoxy resin have been studied using VISAR and PDV multiple-channel laser interferometers. The Hugoniot of epoxy resin and pressure dependence of sound speed has been obtained and it has been shown that the structure of a shock-wave front corresponds to the model of a Maxwell viscous-elastic body with a typical relaxation time of tangential stresses of 0.3 μs. The spall strength has been measured and its dependence on the strain rate in a sample upon pulse tension has been determined.
