Optimization of Apex Shape for Mounting to the Bead Bundle Using FEM.

Tires are one of the most basic and important components of vehicles, including bicycles, cars, trucks, and aircraft. They consist of several layers that provide complex and dynamically changing functions. This work aims to optimize the mounting process of the tire apex to the bead.

Design of a Unique Device for Residual Stresses Quantification by the Drilling Method Combining the PhotoStress and Digital Image Correlation.

This paper presents a uniquely designed device combining the hole-drilling technique with two optical systems based on the PhotoStress and digital image correlation (DIC) method, where the digital image correlation system moves with the cutting tool. The authors aimed to verify whether the accuracy of the drilled hole according to ASTM E837-13a standard and the positioning accuracy of the device were sufficient to achieve accurate results. The experimental testing was performed on a thin specimen made from strain sensitive coating PS-1D, which allowed comparison of the results obtained by both methods.

The utilization of tachymetry in forensic medicine.

Introduction: Tachymetry is a geodetic method enabling to measure angles and distances. The aim of the work was to demonstrate alternatives of its utilization in daily forensic medicine practice. The work is dealing with confusing cases of gunshot injuries.
