net-shape thermoplastic composite: Topics by Science.gov

Advanced Near Net Shape Technology. NASA Technical Reports Server (NTRS) Vickers, John. 2015-01-01. The objective of the Advanced Near Net Shape Technology (ANNST) project is to radically improve near net shape manufacturing methods from the current Technology/ Manufacturing Readiness Levels (TRL/MRL 3-4) to the point where they are viable candidates (TRL/ MRL-6) for shortening the time and ...

No of Download = 846. Abstract. In this research, the compressive, flexural, and shear bond strengths of high strength-high volume fly ash mortar containing high calcium fly ash (HCFA) of various finenesses were studied. The mortars were made from ordinary Portland cement (OPC), HCFA, sand, water, and Type D admixture.

Determining Z/L iteratively, a low rate of convergence was achieved. It was concluded that the divergence of the turbulent transport of TKE was not negligible under unstable conditions. By minimizing the dependence of the calculated neutral drag coefficient on stability, this term was estimated at about -0.65Z/L.

Cyclic Process - Overview, Definition And Examples

A cyclic process is a process in which the initial and final state is the same. The internal energy in a cyclic process is zero. Visit us to know more details of cyclic processes in depth.

1. Introduction. Volcanic edifices are the result of accumulation of deposits from effusive and/or explosive eruptions (Odbert et al., 2015).However, their heterogeneity and rapid growth promote instability: in the worst-case scenario this might result in sector collapse (e.g. Mt. St. Helens, Christiansen and Peterson, 1981).

We present our new designed concentric Hele-Shaw cell geometry with dynamic similarity to a real field wellbore annulus during primary cementing, and then, the results of displacement flow of Newtonian and yield-stress non-Newtonian fluids in it are described. The displacement stability and efficiency, the effect of back, front, and side boundaries on displacement, bypassing pockets of ...
