This paper proposes a simple algorithm for solving the contact problems in relation to sheet stamping. The efficiency and reliability of the algorithm are demonstrated by an investigation of the stamping of elastic-plastic circular plates into a conical die with a hemispherical rigid punch. The analysis shows that the contact stress varies greatly with the punch displacement and deviates from t...

In conventional wire electrical discharge machining (WEDM), WC-Co machined pieces can stay for hours in the worktank. pH range of dielectric Co actively dissolves and thus corrosion occur affecting mechanical properties lifetime those pieces. This study demonstrates how applying cathodic polarization through implementation auxiliary electrodes work zone helps reducing in-depth propagation attac...

This research aims to design a measuring device for the speed and strength of kicks punches in martial arts so that quality can be measured objectively. The types taekwondo were tested ap chagi yeop as well jireugi momtong punches. was conducted several steps, namely: literature study, preparing tools materials, designing modeling, making testing analyzing data. way this tool works, respondent ...

To date, no study has found evidence that the U.S. Supreme Court is constrained by Congress in its constitutional decisions. We addressed the selection bias inherent in previous studies with a statute-centered, rather than a case-centered, analysis, following all congressional laws enacted between 1987 and 2000. We uncovered considerable congressional constraint in the Court’s constitutional ru...

Pressure on Australian universities to meet priorities of the major funding authority continues to exert a dominant influence on institutional management decision making. Because faculties are unequally positioned with respect to the alignment of their core business with changing government initiatives, stresses are created whenever an institution moves to change its own priorities in line with...

The remarkable progress of contemporary technology has a significant impact on the advancement and maturation child. It is important for parent to guide their children activities positive behavior in accordance with basis Al – Qur’an, hadits. This study employs an analytical-descriptive approach, which falls under category descriptive research. involves analyzing interpreting historical account...

A solution of the axisymmetric Boussinesq-type problem is derived for transient thermal stresses in a half-space under heating by using the Laplace and Hankel transforms. An analytical method is developed to predict the temperature field that satisfies the prescribed mechanical conditions. Several simple shapes of punches of arbitrary profile are considered and an expression for the total load ...
