| Summary: | This paper presents the non-linear orthotropic material model of glued-laminated (glulam) bamboo under the flexural bending test. The purpose of modeling was to simulate the non-linear flexural behavior of glulam bamboo in a radial and tangential direction. Glulam bamboo was made of Petung Bamboo (Dendrocalamous Asper). Bamboo properties used for creating a numerical model and validation were obtained from secondary data. The non-linear numerical model was developed based on the flexural test of ASTM D143, Hooke’s Law, Yield Criterion of Tsai-Hill, and Associated Flow Rule for orthotropic material. However, the surface interaction property, hardening function, and damage types have not been defined yet. The 3-dimensional analysis was applied with the total element were 121.600 elements. The result depicts that the flexural behavior of the non-linear numerical model sufficiently meets the result of the experimental study, either in the radial or tangential direction. © 2022, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
