Meshless Structural Analysis of Complex Geometries: XCT-Derived Porous and Non-Periodic Cellular Structures

Abstract

Conventional numerical simulation approaches struggle with the complexity of additively manufactured designs. Bioinspired lightweight structures, variable-density lattices and Xray computed tomographic (XCT) derived defect geometries often exceed the capabilities of finite element workflows. This thesis investigates the Immersed Method of Moments (IMM) as a meshfree alternative, capable of directly simulating on diverse geometries, without complex meshing procedures. To evaluate IMM’s performance a benchmark study was conducted and additionally a XCT-integrated pipeline is developed to simulate porosity from additive manufactured parts. The parts analyzed were generated with using Adaptive Density Minimal Surface cellular structures and evaluated under static loading. Results confirm IMM’s potential is a robust simulation framework for complex structures, such as non-periodic cellular structures.
