A New Model for Converting Short Span Compression with Other Measurements to Ring Crush
نویسنده
چکیده
Linerboard and medium for corrugated packaging has been traditionally marketed on the basis of Ring Crush (RCT) specifications. The current industry trend has replaced manual testing by automated in-line testing which excludes RCT but has basis weight, an ultrasonic stiffness index (TSI), and short span compression (SCT) commonly available. This paper shows how using a combination of these measurements with a non-linear mechanistic theory, equivalent RCT values can be calculated with a good reliability. The model is applied using a wide range of medium and linerboards obtained from 2 mills.

Modeling of Compression Curves of Flexible Polyurethane Foam with Variable Density, Chemical Formulations and Strain Rates
Flexible Polyurethane (PU) foam samples with different densities and chemical formulations were tested in quasi-static stress-strain compression tests. The compression tests were performed using the Lloyd LR5K Plus instrument at fixed compression strain rate of 0.033 s-1 and samples were compressed up to 70% compression strains. All foam samples were tested in the foam rise direction and their ...

AbstractIn this paper, we investigate effect of Fe–intermetallic compounds on plastic deformation of closed-cell composite Aluminum Foam as filler of thin-walled tubes. However, deformation of the Aluminum foam-filled thin-walled tubes as crushed-box will be presented in Part (II). Composite foams of AlSi7SiC3 and AlSi7SiC3-(Fe) as closed cell were synthesized by powder metallurgy foaming metho...

متن کاملOptimization of Multi-period Three-echelon Citrus Supply Chain Problem
In this paper, a new multi-objective integer non-linear programming model is developed for designing citrus three-echelon supply chain network. Short harvest period, product specifications, high perished rate, and special storing and distributing conditions make the modeling of citrus supply chain more complicated than other ones. The proposed model aims to minimize network costs includin...
