Poisson's ratio of plywood measured by tension test

In this research, Poisson's ratio of plywood as obtained by a tension test was examined by varying the width of the specimen. The tension tests were conducted on five-plywood of lauan ( Shorea sp.) with various widths, and Young's moduli and Poisson's ratios of the specimens were measured. 【Get Price】
