Also known as radiata pine veneer, plywood has been increasingly used in different engineering applications and its unique thin structure, with significant mechanical properties, has increased its demand for hybrid deformed structures. The main scope of the present work is to understand the formability characteristics of the plywood with multiple bend axis on the same plane. The properties of wood nullify the normal bending process due to the significant amount of spring-back for the inherent properties of the constituent natural fibres bounded by a predominant lignin component. The process of in-situ curing and post-forming curing were used to achieve the desired folds. Experiment was performed on various plywood samples, with 4-point bending rig, to understand the variation in stress and strain due to variable distances between the bends and the maximum post-curing time. Finally, the overall spring-back analytically varied by 1.96%.  UR - https://aml.iaamonline.org/article_15242.html L1 - https://aml.iaamonline.org/article_15242_6d9283d70c9d0b4b3a1750bd30490638.pdf ER -
