Crack opening analysis of complex cracked pipes
Based on the reference stress approach, two sets of the crack opening displacement (COD) estimation equations are proposed for a complex cracked pipe. One set of equations can be used for the case when full stressstrain data are known, and the other for the case when only yield and tensile strengths are available. To define the reference stress, a simple plastic limit analysis for the complex c...
متن کاملCracked Pipes Alert System for Autonomous Vehicles
Autonomous vehicles will not be driven by a human being. The missing of the human being will make the vehicles less inspected because a human being often listens to the engine and its sounds. A passenger in an autonomous vehicle usually does other things and even sleeps, so the human inspection on the engine and on the pipes system will not be effective. This paper suggests a system that alerts...
متن کاملApplication of Multiple Digital Image Correlation Sensors in Earthquake Engineering
As structural testing has become more expensive, researchers are pushing to capture more and better data with each structural test conducted. Digital image correlation (DIC) is a tool that is gaining popularity as one way to capture more detailed information in testing programs. In threedimensional DIC (3D-DIC), the measured object is photographed with a pair of digital cameras before and after...
متن کاملVisualization of Buckling on Thin-walled Cylindrical Shell by Digital Image Correlation Method
The problem of buckling stability is very important in thin-walled cylindrical shell structure. In order to investigate the buckling phenomena, digital image correlation (DIC) method was applied in this experiment. The specimens have a thickness of 0.131mm and the ratio of external diameter (R0) to thickness (H) R0/H is 252. Due to its curved and thin walled elements, measurement of displacemen...
