Determining temperature and time dependent Poisson’s ratio

WebPoisson’s ratio is defined as the ratio of transverse to longitudinal strains of a loaded specimen. This concept is illustrated in Figure 1. In realistic terms, Poisson’s ratio can vary from initially 0 to about 0.5 (assuming no specimen volume change after loading). WebThis paper presents a brief review of existing literature on the use of Poisson’s ratios in general and by the asphalt research community in specific. The literature review revealed that the majority of existing studies assumed a constant Poisson’s ratio of 0.3–0.35. how to run gradle build in cmd
