Crack Detection in Bearing Plate of Prestressed Anchorage Using Electromechanical Impedance Technique: A Numerical Investigation
نویسندگان
چکیده
The bearing plate is an important part of a tendon–anchorage subsystem; however, its function and safety can be compromised by factors such as fatigue corrosion. This paper explores the feasibility electromechanical impedance (EMI) technique for crack detection in prestressed anchorage. Firstly, theory EMI presented. Next, well-established anchorage literature selected target structure. Thirdly, 3D finite element model PZT transducer–target subsystem simulated, consisting concrete segment, steel anchor head, instrumented with transducer. prestress load applied to via head. response structure numerically obtained under different simulated cracks using linear analysis frequency domain. Finally, resulting was quantified two damage metrics: root-mean-square deviation correlation coefficient deviation. These metrics are then compared threshold identify presence plate. results show that successfully detected tracking shifts metrics. numerical investigation demonstrates potential non-destructive testing method assessing structural integrity structures.

متن کاملNUMERICAL INVESTIGATION OF CRACK ORIENTATION IN THE FRETTING FATIGUE OF A FLAT ROUNDED CONTACT
The growth of slant cracks by fretting fatigue of a half plane in contact with a flat rounded pad was studied. The mode I and mode II stress intensity factors for cracks of various lengths and directions were calculated using the semi-analytical method of the distribution of dislocations, and their cumulative effect on the crack growth was investigated using the strain energy density criterion....

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Development of a Field-Portable Small-Size Impedance Analyzer for Structural Health Monitoring using the Electromechanical Impedance Technique
Electromechanical (E/M) impedance method is emerging as an effective and powerful technique for structural health monitoring. The E/M impedance method utilizes as its main apparatus an impedance analyzer that reads the in-situ E/M impedance of piezoelectric wafer active sensors (PWAS) attached to the monitored structure. Laboratory-type impedance analyzers (e.g. HP4194) are bulky, heavy, and ex...
