Numerical investigation of a star-shaped auxetic structure under different impact velocities

Auxetic structures are a class of mechanical metamaterials characterized by a negative Poisson’s ratio and enhanced energy absorption capabilities under impact loading. In this study, the influence of impact velocity on the mechanical response of a star-shaped auxetic (SSA) structure is investigated using the finite el...

Influence of overheating exposure time on the microstructural stability and mechanical properties of HP40-0.63Nb alloy

HP40-Nb heat-resistant cast steels are widely used for reformer furnace tubes operating at elevated temperatures, where accidental overheating may induce microstructural degradation and alter mechanical properties. This study investigates the influence of overheating time on the microstructure and mechanical properties...
