THE MODE LOCALIZATION PHENOhlENON : VISUAL TEST RESULTS
نویسنده
چکیده
The high degree of manufacturing precision required in space structures may make them more susceptible to mode localization. In this demonstration, the mode localization phenomenon is investigated using an existing full scale antenna-like structure having the complexity, manufacturing precision, and dynamic characteristics of space structures, The actual imperfections were measured and incorporated in a numerical model of the structure. The impact of several parameters that provoke the phenomenon were first studied by numerical simulations, then experimentally. The results show excellent agreement, thereby confirming the importance of mode localization in the design of actual space structure.

TWO-STAGE METHOD FOR DAMAGE LOCALIZATION AND QUANTIFICATION IN HIGH-RISE SHEAR FRAMES BASED ON THE FIRST MODE SHAPE SLOPE
In this paper, a two-stage method for damage detection and estimation in tall shear frames is presented. This method is based on the first mode shape of a shear frame. We demonstrate that the first mode shape slope is very sensitive to the story stiffness. Thus, at the first stage, by using the grey system theory on the first mode shape slope, damage locations are identified in shear frames. Da...
متن کاملAn Enhanced Viscoplastic Constitutive Model for Semi-Solid Materials to Analyze Shear Localization
Semi-solid materials undergo strain localization and shear band formation as a result of granular nature of semi-solid deformation. In the present study, to analyze the shear localization, a unified viscoplastic constitutive model was developed for the homogeneous flow. Then, a linearized analysis of the stability performed by examining the necessary condition for the perturbation growth. For t...

Introduction: FDG Brain PET is a valuable paraclinical tool for presurgical assessments of patients suffering from refractory epilepsy. By the widespread accessibility of PET, recognizing the functional lesions has become a current practical method especially in preoperative evaluations of the partial epilepsy disorders. The aim of our study was to assess the impact of quantit...
متن کاملParathyroid adenoma Localization
Background: Bilateral neck exploration is the gold standard for parathyroid adenoma localization in primary hyperparathyroidism. But surgeons do not have adequate experience for accurate surgical exploration and new methods are developed for surgery like unilateral exploration and minimally invasive surgery, thus, preoperative localization could reduces time and stress in surgical performance....
متن کاملتشخیص آسیب در قاب های برشی با کمک نگره وابستگی خاکستری و جابه جایی ایستایی تخمین زده شده با داده های مودال محدود
In this paper, a new vibration-based damage detection method for damage localization in shear frames is presented. For this purpose, a new damage index is proposed by means of static displacements estimated using only the first several mode data and Grey Relation Theory. The efficiency of the presented method has been demonstrated through studying several damage scenarios on three examples of s...
