A computational model is presented for determining deformations in complexly stressed beams of a structurally non-linear reinforced concrete frame transcendental state caused by special emergency action the form sudden removal one structural elements. The determination stress-strain after formation spatial cracks elements was carried out using calculated section. At same time, dynamic additiona...

Loading rates affect the behavior of concrete specimens from beginning loading process until failure. At rather high rates, longitudinal deformations in under a compressive load are practically elastic up ultimate limit state. It has been previously demonstrated that transverse effectively indicate high-strength entire static range. A theoretical model for cylindrical specimen failure load, bas...

Most studies of the effects of manufacturing defects such as voids have focused on composite strength properties, e.g. the interlaminar strength [1]. The current study investigates how irregularities in the manufacturing process affect progressive damage in the subcritical regime. This effort is along the lines of a broader strategy for performance evaluation of composites coined as defect dama...

A computational study is performed to determine the contribution to ultrasound attenuation in carbon fiber reinforced polymer composite laminates of linear elastic scattering by matrix micro-cracking. Multiple scattering approximations are benchmarked against exact computational approaches. Results support linear scattering as the source of observed increased attenuation in the presence of micr...

Pavement condition assessment is a critical step in road pavement management. In contrast to the automatic and objective methods used for rural roads, most commonly method urban areas development of visual surveys usually filled out by technicians, which leads subjective assessment. Whereas previous studies on identification distresses focused crack detection, this research aims not only cover ...

Most of the existing concrete dams are subjected to cracking. These cracks are caused by various factors such as construction practices, curing, loads and volume change of mass concrete which reduce the efficiency, failure or instability of concrete dams. Using fracture mechanics as a new method to estimate stability and durability of concrete dams is recommended in scientific publications in w...

The problem, generic objectness proposal, aims to reduce the candidate windows for object detection tasks. The popular evaluation criterion for related methods is detection-rate/windows-amount(DR-#WIN), where DR is the percentage of groundtruth objects covered by proposal windows. An object is considered “covered” by a window only if the strict PASCAL-overall criterion [3] is satisfied (the int...

Progressive radial cracking of a clamped plate subjected to crack-face closure is studied. The material behavior is assumed to be elastic-brittle. The cracks are assumed to be relatively long in the sense that the three-dimensional contact problem can be described via a statically equivalent two-dimensional idealization. The number of cracks is supposed large enough to permit a quasi-continuum ...
