Predicting time-to-failure in rock extrapolated from secondary creep
Stress relaxation experiments are reported that culminate in energetic failure in rocks analogous to the loading cycle and subsequent localization or reactivation on brittle faults embedded in an elastic medium. Universally, rapid primary deformation arrests and transitions into a long secondary deformation phase that ultimately accelerates to catastrophic rupture. Primary deformation (u) confo...
متن کاملDigital Image Correlation combined with Electronic Speckle Pattern Interferometery for 3D Deformation Measurement in Small Samples
The small size of mesoand microelectromechanical systems (MEMS) devices presents several challenges for full-field deformation measurements. A hybrid system combining Digital Image Correlation (DIC) for in-plane deformation and Electronic Speckle Pattern Interferometry (ESPI) for out-of-plane deformation measurements has been developed for working with these small size scales. Measurement of th...
متن کاملQuality assessment of speckle patterns for digital image correlation
Digital image correlation (DIC) is an optical-numerical full-field displacement measuring technique, which is nowadays widely used in the domain of experimental mechanics. The technique is based on a comparison between pictures taken during loading of an object. For an optimal use of the method, the object of interest has to be covered with painted speckles. In the present paper, a comparison i...

در این رساله با معرفی سقف های psscb متشکل از ترکیب ورق های فولادی ذوزنقه ای و تخته های سیمانی الیافی به عنوان سقف های پیش ساخته (سازگار با سیستم سازه ای قاب های فولادی سبک) به بررسی پارامترهای موثر بر صلبیت سقف، پرداخته می شود. در تحقیق حاضر ابتدا به مدل سازی دو نمونه سقف آزمایش شده، به روش اجزاء محدود با استفاده از نرم افزار تحلیلی abaqus ver 6.10 پرداخته شده است. نمونه های ساخته شده تحت اعما...
Digital Speckle Pattern Interferometer for Measuring Micro Deformation Area
Nondestructive testing(NDT) and inspection of structural materials are becoming increasingly important to assure the safety level in the present industries. Nondestructive measuring techniques using an optical interferometer have emerged as a valuable tool for many industrial applications [1]. This non-contact optical method is a full-field measurement technique with high speed [2]. Recently, b...
