Fracture Behavior of Ceramic Filter Using Diametral Ring Compression Test.

Fracture Behavior of Advanced Ceramic

Microstructural, mechanical, and thermal-shock behavior of hot-gas candle fiters obtained from different manufacturers have been evaluated. These filters include both monolithic ceramic and composite materials. Based on the results obtained so far, composite filters perform better than monolithic ceramic filters in a thermal-shock environment. During thermal-shock testing, the monolithic cerami...

Diametral compression of pultruded composite rods

Diametral compression tests were performed on pultruded composite rods comprised of unidirectional glass or carbon fibers in a common matrix. During compression tests, acoustic emission (AE) activity was recorded and images were acquired from the sample for analysis by digital image correlation (DIC). In both composite systems, localized tensile strain developed in the transverse plane under th...

FRACTURE BEHAVIOR OF A Si3N4-BN FIBROUS MONOLITH CERAMIC

EVALUATING HOT DEFORMATION BEHAVIOR OF W360 TOOL STEEL BY HOT COMPRESSION TEST

In this research, the hot deformation behavior of W360 tool steel was investigated using hot compression test at 1000-1200°C and strain rates of 0.001, 0.01, 0.1, and 1 s-1. According to the results, dynamic recrystallization was found the most important restoration factor of this alloy during hot deformation. Recrystallization was enhanced with an increase in temperature and strain rate. Also,...

Determination of Friction Coefficient by Employing the Ring Compression Test

The main objective of this research was to investigate the effect of material properties, strain-rate sensitivity, and barreling on the behavior of friction calibration curves. The compression tests were conducted to obtain the necessary material properties for the finite element analysis. A series of ring compression tests were then conducted in order to determine the magnitude of the friction...
