RISDirect Measurement of Traction–Separation Law of Concrete–Epoxy Interfaces Subjected to Moisture Attack under Mode-I Loading
Publisher: American Society of Civil Engineers
Abstract: A proper traction–separation law based on the physical behaviors of the concrete–epoxy interface is needed to simulate the debonding behavior of fiber-reinforced polymers–strengthened concrete structures. However, no method ...
Mechanics of Bimaterial Interface: Shear Deformable Split Bilayer Beam Theory and Fracture
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A bi-material or bi-layer system is a common configuration in structural applications, and it is usually manufactured by monolithically forming the two parts together. Interlaminar delamination ...
Mechanics of Composite Sinusoidal Honeycomb Cores
Publisher: American Society of Civil Engineers
Abstract: Lightweight and heavy-duty fiber-reinforced polymer (FRP) composite honeycomb sandwich structures have been increasingly used in civil infrastructure. Unique cellular core configurations, such as sinusoidal core, have been ...
Fracture Analysis of Shear Deformable Bi-Material Interface
Publisher: American Society of Civil Engineers
Abstract: Based on a novel split bi-layer shear deformable beam model capable of capturing the local deformation at the crack tip, the explicit closed-form solutions of bi-material interface fracture are presented in this paper. A ...
Local Buckling of Composite FRP Shapes by Discrete Plate Analysis
Publisher: American Society of Civil Engineers
Abstract: An analytical study of local buckling of discrete laminated plates or panels of fiber-reinforced plastic (FRP) structural shapes is presented. Flanges of pultruded FRP shapes are modeled as discrete panels subjected to ...
Closure to “Local Buckling of Composite FRP Shapes by Discrete Plate Analysis” by Pizhong Qiao, Julio F. Davalos, and Jialai Wang
Publisher: American Society of Civil Engineers
Environment-Assisted Subcritical Debonding of Epoxy-Concrete Interface
Publisher: American Society of Civil Engineers
Abstract: Interface debonding can grow slowly within the FRP-to-concrete interface in aggressive environments, even though the energy release rate at the crack tip is only a fraction of the critical energy release rate of the ...
Mixed-Mode Fracture of Hybrid Material Bonded Interfaces under Four-Point Bending
Publisher: American Society of Civil Engineers
Abstract: A combined analytical and experimental approach is presented to characterize mixed-mode fracture of hybrid material bonded interfaces under four-point bending load, and closed-form solutions of compliance and energy release ...
Local Delamination Buckling of Laminated Composite Beams Using Novel Joint Deformation Models
Publisher: American Society of Civil Engineers
Abstract: Local delamination buckling formulas for laminated composite beams are derived based on the rigid, semirigid, and flexible joint models with respect to three bilayer beam (i.e., conventional composite, shear-deformable ...
Exploring Tea Polyphenols as a Performance Enhancer for Cement Mortars
Publisher: American Society of Civil Engineers
Abstract: This study draws inspiration from the chelating abilities of dopamine and tannic acids with Ca2+ in cement-based materials and explores the potential of green tea water (GTW) with tea polyphenols (TP) as the major soluble ...
