Bamboo is a natural composite material. It is called a natural composite material because it’s consisted of fibers made of cellulose and the matrix is lignin. Cellulose acts as a reinforcing structure and increases the stiffness of bamboo. Mostly, bamboo is applied as a building structure and decoration. This is because there are still many properties of bamboo material that are not yet known. On this basis, so this research was carried out as a method to determine the mechanical properties of bamboo. This research will focus on numerical simulation of tensile strength test perpendicular to fiber direction of Gigantochloa apus using ABAQUS/CAE software with Extended Finite Element Method (XFEM) to visualize failure and crack propagation as validation toward the experimental results. The results that are compared between numerical simulations and experiments are in the form of load-displacement curves. From the curve, the maximum loading value will be obtained to determine the average tensile strength in the direction perpendicular to fiber. Based on the numerical simulation, the maximum load of 2.81 kN will be obtained so that the magnitude of the tensile strength perpendicular to the fiber for Gigantochloa apus is 2.09 MPa.
