摘要：

SrTiO3 single crystals have been studied by quasistatic twist-torque (shear strain-shear stress) and by low-amplitude torsional resonance experiments around 10 kHz. The hysteresis loops of the tetragonal low-temperature phase are interpreted in terms of ferroelasticity. The low-amplitude elastic data shows anomalies between 30 and 50 K with strong nonlinear contributions.
