in reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. in this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

AIM To assess the survival rate of root filled cracked teeth over a 2-year period in a tertiary institute. METHODOLOGY Forty-nine patients who had root canal treatment completed on their cracked teeth at the National Dental Centre (Singapore) were recalled for a 2-year review. Collected review data included presence of periodontal pocketing, sinus tract and swelling associated with the teeth....

We study linear dynamics of an initially parabolic arch deformed by a uniform ‘dead’ load. The is seen as fully deformable one-dimensional continuum with rigid cross-sections, one which suffers from small local crack at its boundary. simulated springs, the stiffnesses are evaluated via stress intensity factors. By two first-order perturbations we investigate non-trivial equilibrium adjacent to ...

An assessment is made here of the role played by the micropolar continuum theory on the cracked Brazilian disc test used for determining rock fracture toughness. By analytically solving the corresponding mixed boundary-value problems and employing singular-perturbation arguments, we provide closed-form expressions for the energy release rate and the corresponding stress-intensity factors for bo...
