A LATERAL DEFORMATION TRANSDUCER FOR TRIAXIAL TESTING: RESEARCH NOTE

As research is expanding into more detailed study of stress–strain behavior of soils in the triaxial test, it is necessary to develop new techniques for measuring more accurately loads and deformations. However, the necessary measuring equipment is not always available commercially. The writers have developed a transducerized apparatus to measure the diameter of triaxial samples, and information on the design and characteristics are presented in this research note.
