Manufacturing Process Effects on Multiaxial Mechanical Behavior and Anisotropy Evolution of Fiber-Reinforced Polymer Composites for Automotive Applications

This study establishes a clear process-structure-anisotropy relationship by demonstrating that vacuum-assisted resin transfer molding (VARTM) generally enhances fiber volume fraction and stiffness-dominated behaviors in carbon, glass, and basalt fiber-reinforced polymer composites compared to hand layup, while significantly influencing multiaxial mechanical properties and anisotropy indices critical for optimizing lightweight automotive structures.

Secondary Consolidation: A Novel Approach to an Old Problem

This research proposes a novel approach that links soil pore size distribution to water flow dynamics, demonstrating that primary consolidation occurs in macropores while secondary consolidation arises from micropore flow, thereby enabling the prediction of total settlement without requiring long-term tests.

Efficient finite element quadrature on immersed voxel data

This paper presents an efficient voxel quadrature scheme based on a modified moment-fitting approach that computes custom integration rules to absorb voxel information directly into weights, enabling exact stiffness matrix integration for locally refined finite element spaces while decoupling material resolution from the basis and outperforming traditional pre-integration and composed Gauss-Legendre methods.
