Properties and Specifications of Materials for Radial Shim Design by Haris Kokkinos

This document presents a comprehensive analysis of various materials utilized in the design of symmetric radial shims, focusing on properties such as elasticity and thermal expansion coefficients at different temperatures. Key materials included are stainless steel (multiple grades), titanium alloy, copper, and insulation materials like Kapton. The shim dimensions and displacements are thoroughly detailed, along with solutions for contact pressures and mechanical stops. This analysis aims to provide insights necessary for effective shim design in engineering applications.
