Elastic anomalies accompanying phase transitions in (Ca,Sr)TiO3perovskites: Part I. Landau theory and a calibration for SrTiO3 by Michael A. Carpenter (vol. 92, p. 309–327, 2007: DOI 10.2138/am.2007.2295).

Carpenter (2007a, 2007b) and Carpenter et al. (2007) used Landau theory to develop a general treatment for variations of elastic moduli that are expected to accompany structural phase transitions due to octahedral tilting in perovskites. The well-established concept is, first, that an externally applied stress induces a strain according to Hooke’s law. If a phase transition can also occur, there may be an additional relaxation that is due...
