Even though steel bar is a conventional reinforcement in soil stabilization systems, the problem of corrosion of steel may lead to vast damages especially in aggressive environments. In the past decades, Fiber Reinforced Polymer (FRP) materials have offered an effective solution to overcome the corrosion problem. Despite numerous bond stress-displacement models for reinforcements in concrete, t...

A finite element study carried out using LS DYNA and aimed to simulate the monotonic pull-out test of deformed steel rebar embedded in concrete is presented this paper. Three models interface between well-confined concrete, i.e. perfect bond model two bond-slip are observed compared. Bond stress-slip response obtained numerically validated with experimental data empirical equations available fr...

In the current research, a three-dimensional finite element model was considered to predict the mechanical behavior of Single Wall (SWCNTs) and Multi Wall Carbon Nanotubes (MWCNTs). Assuming the nonlinear elastic behavior of C-C bond in large strains, hyperelastic models were considered. Literature review revealed that the material parameters of the hyperelastic models have been determined from...

(2001) Effect of bond thickness on fracture behaviour in adhesive joints. To study the effects of bond thickness on the fracture behaviour of adhesive joints, experimental investigation and finite element analysis have been carried out for compact tension (CT) and double-cantilever-beam (DCB) specimens with different bond thickness. Fractography and fracture toughness exhibited apparent variati...

<p style='text-indent:20px;'>This paper considers the 3D printing process as a discontinuous control system and gives simple coherent bond stress-slip model for new intelligent building 3-D printed concrete. The previous models focused on either maximal stress or slip, however, novel uses an energy approach by dimension analysis, so that main factors affecting relationship can be clearly ...

Objective: Several research studies have explored the correlation between postpartum depression and a weak mother-infant bond. However, fewer studies have analyzed how other postpartum mental health conditions, such as childbirth-related post-traumatic stress disorder (PTSD), or important personal characteristics such as adult attachment styles, affect the quality of the mother-infant bond. The...

This paper develops a stress-testing model to value defaultable bonds under stressful market conditions. Default occurs when some signaling process hits a pre-defined default barrier. The signaling variable is considered to be some macro-economic variables such as foreign exchange rates. The dynamics of the default barrier depends on the volatility and the drift of the signaling variable. We de...

This paper presents the coating thickness effect on the stress distribution of a coated cylinder head. A typical thermal barrier coating was applied on a diesel engine cylinder head. Thus, the residual stress which occurred during the plasma thermal spraying was also considered. The coating system consisted of two layers a metallic bond coat and a ceramic top coat. The bond coat thickness is co...
