Abstract
Due to their low weight and superior energy absorption,
functionally graded porous structures have been used
recently. In the fields of engineering, biomedicine, and
aerospace, they have a variety of uses. Therefore, the
researchers aim to reduce costs by balancing material
strength and lightweight. To study the impact of the porosity
gradient through thickness, samples of PLA material were
designed and created using a 3D printer by international
standard specifications. An experimental three-point
bending test was performed, and then simulations were
performed using ANSYS 2022 R1 software on samples with
functionally gradient different porosity layers to verify the
experimental results.The results from the experiment and
the numerical values were aligned with an error rate of no
more than 13%. The maximum bending load and maximum
deflection of the beam were specified experimentally and
compared with the numerical solution. The maximum
bending on the minimum deflection When the porosity layer
in the middle of the beam matched the ideal maximum
bending load (190,194) N experimentally and numerically,
respectively. The minimum deflection (5.9,6.4) mm
experimentally and numerically, respectively, was obtained
in samples with varying porous layers.
