Plough hitch parameters for smooth tails

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Qualitative and energy performance of a plough largely depends on the parameters of the plough linkage mechanism. The aim of the research is to substantiate the parameters of plough linkage for smooth sloughing, which turns the layers within its furrow to a tractor of 1.4 classes. In researches methods of classical mechanics are

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for
