Orthotropic Modeling of Nonlinear Interlayer Adhesion (OMNIA)
Joseph M. Perry
Fusion Deposition Modeling (FDM) is a versatile additive manufacturing technique that enables rapid prototyping of complex geometries and supports a wide range of materials. However, FDM parts are inherently anisotropic due to their layered construction. When evaluating part feasibility, Finite Element Analysis (FEA) must accurately account for this anisotropy by creating an orthotropic material model. The mechanical properties of FDM parts are strongly influenced by slicer parameters such as ex
