Optimizing Charpy Impact Strength of Material‐Extruded PLA Through Layer Height, Raster Angle, and Infill Geometry

Journal of Applied Polymer Science, EarlyView.
Charpy impact performance of material‐extruded PLA is governed by the coupled effects of layer height, raster angle, and infill geometry. Full‐factorial testing identifies layer height as the dominant factor and reveals a strong layer‐height–raster‐angle interaction.

Integrating Crashworthiness into the Concept Design Phase of Tanker Structural Design Through Surrogate-Based Optimization

Journal of Marine Science and Engineering
A key limitation of conventional early-stage oil tanker structural design is that the accidental limit state performance is rarely included as an explicit design objective, even though major topology and arrangement decisions are taken before detailed ...

Influence of Hybrid Co‐wrapped Yarn Structure on the Energy Absorption and Crack Propagation Resistance of Fiber‐Reinforced Composites

Polymer Composites, EarlyView.
Helical wrapping of polyamide around E‐glass fibres deflects and bridges impact‐driven cracks, arresting damage that would otherwise propagate catastrophically in conventional side‐by‐side hybrid yarns. ABSTRACT Hybrid cowrapped (CW) yarns were engineered to enhance the impact resistance and damage tolerance of fiber‐reinforced composites.

Crash Behavior of DP800–DP1000 Advanced High‐Strength Steel’s Dissimilar Resistance Spot Welded Joints Under Quasi‐static and High Strain Rates

steel research international, EarlyView.
The high‐strain‐rate behavior of resistance spot‐welded DP800–DP1000 joints is investigated. Results show that microstructural gradients across BM–HAZ–FZ govern hardness, strain rate sensitivity, and failure modes. While strength increases with strain rate, energy absorption is controlled by ductility, with DP800–DP800 joints showing superior ...
