Investigation of Contact Pressure Distribution on Sheet Metal Stamping Tooling Interfaces: Surface Modeling, Simulations, and Experriments
Contact Pressure Distribution Sheet Metal Stamping Tooling Interfaces Surface Modeling Simulations Experiments
2014/10/23
In stamping operations, sheet metal is formed into a desired shape by pressing it in a hydraulic or mechanical press between suitably shaped dies. As a predominant manufacturing process, sheet metal f...
The impact of the Weibull distribution on the performance of the single-factor ANOVA model
ANOVA robustness Weibull ANOVA normality assumption Shape parameter Scale parameter Normality violation
2010/9/14
This paper conducts a simulation study of the effects of violating the ANOVA normality assumption in the presence of Weibull data. Twelve specific Weibull distributions, characterizing the life data o...
