Analysis of Melt-Pool Behaviors during Selective Laser Melting of AISI 304 Stainless-Steel Composites

open access: yesMetals, 2019
The melt-pool behaviors during selective laser melting (SLM) of Al2O3-reinforced and a eutectic mixture of Al2O3-ZrO2-reinforced AISI 304 stainless-steel composites were numerically analyzed and experimentally validated. The thermal analysis results show

COMPOSITE REINFORCEMENT FOR REINFORCED SOIL APPLICATIONS

open access: yesSOILS AND FOUNDATIONS, 2003
Composite reinforcements achieve the desired performance with a synergetic action from two components. In this paper, development of a composite reinforcement system, made of high tensile steel wire, encased in a cement mortar as a viable system for soil reinforcement applications is proposed.

REINFORCEMENT MAGNITUDE AND THE INHIBITING EFFECT OF REINFORCEMENT [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1979
In a two‐key concurrent variable‐interval schedule (using pigeons), if the reinforcement frequency for one response is held constant while that for the other is increased, the rate of response on the constant key decreases. The immediate reinforcement for key pecking can usually be conceptualized as the change from a condition in which the key light is
