The thermal deformation problem is quite serious for the workbench of environmental dry hobbing machine due to accumulation hot chips. A better understanding quantity and optimization chip repose angle necessary reduce deformation. Hence, this paper focuses on modeling machine. Firstly, dynamic flow characteristics chips are clarified by analyzing generation mechanism motion trajectory hobbing....

A susceptibility function χ(L) is introduced to quantify some aspects of the intermittent stick-slip dynamics of a rough metallic cylinder of length L on a rough metallic incline submitted to small controlled perturbations and maintained below the angle of repose. This problem is studied from the experimental point of view and the observed power-law behavior of χ(L) is justified through the use...

Here, we investigate the ultrastructural origins of the strength of bone, which is critical for proper physiological function. A combination of dual nanoindentation, three-dimensional elastic-plastic finite element analysis using a Mohr-Coulomb cohesive-frictional strength criterion, and angle of repose measurements was employed. Our results suggest that nanogranular friction between mineral pa...

Starch is a carbohydrate that can be used as binder in pharmaceutical preparations. Paracetamol has poor flowability and compactibility with its crystalline form, it necessary to make granules by wet granulation method starch binder. This study banana peel waste (Musa paradisiaca) source of starch. Three granule formulations (F1, F2, F3) were prepared using the concentrations 5% (F1), 8% (F2), ...
