Assessing the flexural strength changes in decayed wood of Iranian beech (Fagus orientalis) by using of nondestructive stress wave method
The aim of this study was to evaluate sound and decayed wood of Iranianbeech (Fagus orientalis) with a nondestructive stress wave method. Wood samples,with dimensions of 9 by 19 by 200 mm were decayed in laboratory soil-bed tests,based on European pre-standard ENV-807. The decay was evaluated by measuringbending dynamic modulus of elasticity (MOEd) and longitudinal dynamicmodulus of elasticity ...

In this paper, we researched visualization of guided wave propagation in pipe with defect. The characteristic of three-dimensional sound field is simulated by finite element method. First, the characteristics of many modes of guided wave propagation in pipe and the interaction of guided wave with defect is studied. Then, the model of scattering sound field for defect exist is builded when guide...
متن کاملDesign of Nondestructive System for Hardness of Carbonitrided Steel Parts Using Eddy Current Testing Method: Case study on the Tappet Parts
In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...

Guided waves have been increasingly used in nondestructive evaluations. Guided waves have shown to be specially promising in the testing of pipelines and tubing systems due to the ability of propagating long distances. Recent advances on guided wave pipe inspection focus on the understanding and utilization of guided wave flexural modes. This paper discusses and compares the technologies curren...
متن کاملAn Optical Measurement System to Measure Velocity and Provide Shock Wave Pressure Diagrams
This paper introduces an optical measurement system for shock wave characteristics. The system works by mountinga metal plate attached to spring mounts against the shock wavefront. This set is sealed and can plot the shock wave pressure diagram by measuring plate's displacement, radiation and changing the reflection of light during shock wave conflict, and converting these optical data to volta...
