Small strain stiffness of tested geomaterials is evaluated by newly developed large-size disk transducer method and small-strain cyclic loadings. Stiffness measured by both static and elastic wave measurement is confirmed to be followed similar trends. The large size disk transducer evinces the competent performance showing the stiffness evaluated by this method scattered within 20% of the stiffness achieved by a static method and compared with available previous researches as well.]]> Mon 16 Nov 2020 17:25:51 AEDT ]]>
