Steel Under Strain Hardening
Abstract: Dislocation is crystal lattices dis-organization to absorb energy or to change atomic allocation to lower most energetic position. Mild steel studies confer sessile of such dislocation forests is limit for infinite dislocation multiplication or yield drop, which further limit at tensile strength. In usual cases this strain hardening either have no require or require in sharp cases or tend to get strain harden like crash boxes of auto-sectors. High strength …

Mechanical Behaviour of AISI 204 Cu Metastable Low Nickel Austenitic Stainless Steel Sheets at Various Constantly Maintained Elevated Temperatures
Abstract: Mechanical behaviour of AISI 204 austenitic stainless steel is analyzed at 298-873K and also a comparison with that of AISI 304 is done. Room temperature tensile properties are obtained based on an average of properties evaluated on specimens prepared with specimen length axes at 0°, 45° and 90° to sheet rolling direction. Room temperature flow curves are obtained as a function of nickel content and sheet thickness. High temperature tensile …

Contributing factors in the initiation of failure of asphalt concrete
Abstract: As long as the asphalt concrete pavement is under service, signs of failure usually initiate and the distress types start showing throughout the service life. The asphalt concrete pavement practices repeated tensile and shear stresses through the vehicular loading. In the present study, the contributing factors in the initiation of failure under repeated flexural stresses have been detected. Slab samples of Asphalt concrete have been prepared at the laboratory by …

Mechanical Performance Degradation of Naturally Aged Nitrile Butadiene Rubber in Low Frequency Range...
Abstract: For good mechanical design, damping is often still an invisible requirement. Nitrile Butadiene Rubber (NBR) has a wide range of applications as a damping and sealing material. To offer the long-term service of NBR, it is important to estimate the degradation of modal properties under complex mechanical and environmental loading. The present work aims to correlate the experimental data with generalized higher-order Maxwell models and curve fitting techniques to find …

Dynamic Behavior of Recycled Asphalt Concrete
Abstract: Utilizing reclaimed asphalt pavement (RAP) in new asphalt mixtures has increased in recent years because of its economic and environmental benefits. The dynamic behavior of the recycled asphalt concrete (with cutback and emulsion) in terms of resilient modulus (Mr), rutting resistance, and permanent microstrain have been investigated in this work. Cylindrical specimens of 102 mm in diameter and 102 mm in height have been prepared from the recycled mixture after …
