Estimating materials

Calculator An interactive process wizard that provides quick, effective material, design, processing, and cost solutions. This Engineering Calculator s capabilities include (1) Material, to select from a variety of GE Plastics materials (2) Design, which calculates minimum part thickness based upon allowable deflection (3) Processing, which calculates pressure to fill and clamp force and (4) Cost, which calculates estimated material and processing costs for the intended part. 

To estimate material-specific emissions from the waste treatment processes, landfill and incineration, of EoL cushion vinyl floor covering a supporting spreadsheet of Ecoinvent is used. The results will depend on the assumptions that are made in these models. In this project these assumptions are not studied in detail. Necessary data for the calculation of the burden are, e.g. element composition, water content, energy content, degradability in landfill, etc. Note that the Ecoinvent waste management model estimates emissions based on the element composition and some general characteristics of the materials (like degradability).

Naturally, the effect of the chemical nature of polymers on the flammability may be established only in tests under identical conditions. At present, many procedures are available for estimating material flammability, each reflecting one or another aspect of the complex combustion process. 

Fractions are used to allow comparison of the nugget-effect value to the estimated material variation. 

Given your best estimates for sales and production, estimate material usages and negotiate for a price based on that volume. Remember, the estimate should be the best you have and not inflated to try to get a better price from the supplier. 

Large quantities of end-of-life electronic and electrical (E E) equipment are now beginning to appear in the electronics industries. Micro-waves and television sets are the major contributors to this at present but computers may well overtake these due to the very high rate of obsolescence in this industry. The estimated materials value of the materials currently used in the E E industry, much of it in the form of battery materials, is 50 M per annum and there is a strong incentive... 

The simulation of friction does not only call for appropriate friction models, but also for an in-depth knowledge of material behavior. Due to the extreme deformation conditions in the flow layer, there are hardly any material parameters available to enable their simulation. An attempt was made to estimate material data in the flow layer by comparing FEM simulations with... 

CAD systems are also useful for estimating material costs. The CAD software will have libraries of different materials that allow an engineer to compare the cost, strength, and... 

Each of the estimated material can be used in prosthodontic treatment in patients, depending on the necessity of relieving the prosthetic base. 

For maximum estimated material transfer rates achievable in conversion and fabrication facilities, it was determined that, at best, a maximum ramp rate of a few cents per second was possible hence, the system was incapable of sustaining a superprompt critical excursion under these normal" flow conditions. 

Assistance for process yield estimation, material balance and cost of production. 

Perform a material balance on the plant or pilot plant. Include assumed reactant conversions and estimated material yields. Incorporate possible ionic and water transport between catholyte and anolyte, vaporization losses and precipitation, etc.

Nestleroth et al. [15], Segal et al. [16] considered some established novel signal processing schemes to assist in adhesive bond inspection. Sinclair et al. [17] and Filimonov [18] employed acoustic resonance methods for dynamic elastic modulus measurements in adhesively bonded structures. Yost and Cantrell [19], Achenbach and Parikh [20] and Nagy et al. [21] considered a nonlinear response of bonded structures to estimate material characteristics. In Achenbach and Parikh [20], failure was preceded by nonlinear behavior of thin boundary layers at the interfaces. Billson and Hutchins [22] considered lasers and EMATS in bond investigations. It was shown that this non-contact technique was reasonable when compared to that obtained by conventional piezoelectric transducers. Ince et al. [23] also characterized bonds with laser-generated ultrasound and through-transmission measurements. 

EPRI has developed Guidelines for FGD Material Selection and Corrosion Protection (TR-100680) (Rosenberg et al., 1993), which includes a materials experience database at operating U.S. FGD plants. They have also developed software for estimating material costs (CS-3628, Cloth, 1984).
