Modeling Moisture-Induced Damage in Asphalt Concrete
… (AC) is not new but an unsolved problem. For decades laboratory studies have been conducted on both loose and compacted mix to understand the effects of moisture on the AC damage. Adhesive and cohesive damages are the two major types of damages occur inside the AC. Adhesive damage is a …

Process modeling for solidification microstructure and transient thermal stresses in laser aided DMD process
"Despite enormous progress in Laser Aided Direct Material Deposition (DMD) process adverse effects of process parameters on variety of properties and microstructure have been reported. De-bonding at substrate-deposition interface and cracking in deposited layers are a few that occur due to …

2-D NON-LINEAR FINITE ELEMENT ANALYSIS OF FOLSOM DAM: SEISMICALLY INDUCED SEPARATION AND PORE PRESSURE ALONG THE SOIL-CONCRETE INTERFACE
… during a seismic event has not been well understood. During a ground shaking, bonding and de-bonding action along the interface may cause significant separation of soil and concrete surfaces, and such a separation may take place at any depth along the interface creating a stability concern …

A Predictive Methodology for Soft Impact Damage in Jet Engines Incorporating Hybrid Composite Structures
This work presents a detailed predictive modeling methodology for comprehensive crashworthiness analysis of advanced jet engine forward sections, containing hybrid and composite structures, when subjected to soft impact. Bird strike onto the fan assembly is chosen as the impact event to be studied. …

Flexural behaviour of continuously supported FRP reinforced concrete beams.
… enhancing the load capacity, and reducing the deflection of such beams. However, continuous concrete beams reinforced with CFRP bars exhibited a remarkable wide crack over the middle support that significantly influenced their behaviour. The ACI 440.1R-06 equations have been validated against …

Shear Strengths of Three "One-Step" Self-Etching Dental Bonding Agents
<p>Objective: To compare the dentin shear bond strength of three self-etching bonding agents with that of a conventional total-etch bonding system.</p> <p>Materials & Method: Extracted third molars (120) were fixed in 10% formalin and randomly divided into eight groups of 15 specimens each. The …

Development of a testing approach for tack coat application rate at pavement layer interfaces
Pavement interlayer bonding is one of the critical factors that affect the pavement service life. In addition to difficulties in compaction, lack of interface bonding can lead to serious pavement deterioration including slippage cracking, de-bonding, and early fatigue cracking, all of which …

SIGNIFICANCE OF U-WRAP FRP SHEAR STRENGTHENING ON FLEXURAL BEHAVIOR OF RC BEAMS STRENGTHENED USING NEAR SURFACE MOUNTED FRP BARS
… the performance of NSM-FRP technique is strongly dependent on bond performance between adhesive-concrete and adhesive-FRP interface. Although a full development length is provided for the NSM FRP bar, rupture of the FRP bar is highly unlikely. This is attributed to the fact that the NSM FRP bar …
