Damage Mechanism of Braid Hole Composite Bolt Joints Under Quasi–Static Tension

Analysis of Stress Evolution and Failure Behavior in the Intra-Holes of CFRP/Ti Laminate Bolted Joints

Dynamic tensile failure of CFRP/aluminum bolted joints: Experimental and numerical investigation

The dynamic tensile failure of composite/metal bolted joints is governed by the coupled effects of stress concentration, local contact deformation, and rate-dependent damage evolution. In this study, single-bolt CFRP (Carbon Fiber Reinforced Polymer)/7075 aluminum joints are found to exhibit a pronounced strain-rate...

Multi-scale crushing response of sandwich composite connecting rod based on thermal expansion molding technique

The lightweighting of automotive chassis structural components faces multiple challenges, including the selection of molding processes, the design of lightweight material structures, and the joining methods between metals and composites. In this study, a steel rear suspension link of an automotive chassis is taken as t...

Modeling Crack Behavior around Holes in Glulam Beams Using the WoodST Constitutive Model Based on Continuum Damage Mechanics

The integration of service holes in glulam beams is increasingly common in mass timber construction; however, these openings introduce stress concentrations that can compromise structural integrity through crack initiation and propagation. This study presents a robust numerical framework for simulating crack behavi...

Open-hole flexural damage response of Z-fiber reinforced hybrid woven composites

Drilled holes and through-thickness reinforcement influence the mechanical behavior and damage propagation of load-bearing composite structures. This study examines the combined effects of hole diameter, inter-layer hybridization, and stitching on the flexural response and internal damage propagation of woven composi...

Finite Element Analysis of Controlled-Slip Bolted Shear Connectors for Interface Deformation Coordination in Negative-Moment Regions of Steel–UHPC Composite Beams

To improve deformation compatibility in the negative-moment regions of continuous steel–ultra-high-performance concrete (UHPC) composite girders, this study investigates a controlled-slip bolted shear connector in which bolt-hole clearance is intentionally used as a deformation-release parameter. A three-dimensional no...
