• In this research, in-plane shear moduli of plywood as obtained by a tension test of [±45] off-axis specimen were examined by varying the width of the specimen. The tension tests were conducted on five-plywood of Lauan (Shorea sp.) with various widths, and in-plane shear moduli of the specimens were measured. Flexural vibration tests and finite element calculations were independently conducted. A comparison among the results of the experimental and numerical analyses revealed that specimen should be wide and the gauge should have an appropriate length with respect to the specimen width to measure the in-plane shear modulus appropriately with reducing the influence of variation of normal strain in the width direction.
