Three-parameter, elastic foundation model for analysis of adhesively bonded joints
Jialai Wang,Chao Zhang +1 more
TL;DR: In this article, a three-parameter, elastic foundation model is proposed to analyze interface stresses of adhesively bonded joints, which does not satisfy the zero-shear-stress boundary conditions at the free edges of the adhesive layer.

Novel joint deformation models and their application to delamination fracture analysis
Pizhong Qiao,Jialai Wang +1 more
TL;DR: In this paper, three joint deformation models (i.e., the rigid, semi-rigid, and flexible joint models) describing the different degrees of crack tip deformation are obtained based on three corresponding bi-layer beam theories (e.g., the conventional composite beam, shear deformable bi-layered beam, and interface deformable beam).

Field performance of concrete pipes during jacking in cemented sandy silt
TL;DR: In this paper, the authors present the field performance of concrete pipes during the jacking carried out under the Guan River in Jiangsu, China, and propose a normalized jacking force to evaluate the additional rebar stress in jacking pipes.

Debonding analysis of FRP–concrete interface between two balanced adjacent flexural cracks in plated beams
TL;DR: In this article, a bi-linear cohesive interface modeling approach was adopted to characterize the stress-deformation relationship of the FRP-concrete interface, and closed-form solutions of bond slip, interface shear stress, and axial force of FRP in different stages were obtained.

Interface crack between two elastic layers
Zhigang Suo,John W. Hutchinson +1 more
TL;DR: In this article, a semi-infinite interface crack between two infinite isotropic elastic layers under general edge loading conditions is considered and the problem can be solved analytically except for a single real scalar independent of loading, which is then extracted from the numerical solution for one particular loading combination.

An augmented double cantilever beam model for studying crack propagation and arrest
TL;DR: In this paper, an improved analytical model for the double cantilever beam fracture specimen is developed by treating a finite length beam which is partly free and partly supported by an elastic foundation.
