In recent years, high-strength steel has been used extensively for infrastructures because of its many advantages, such as ductility and strain-hardening properties, which are inferior to those ordinary structural steel, the small dimensions elements, lead greater freedom elegance in design, resulting lighter structures. practice, imperfections residual stresses due welding process pre-buckling...

Cylindrical shell is a common structural design solution in many engineering fields, such as the foundation supporting structures and buoyant column of offshore wind turbine maritime sector. Operating an ocean environment, these cylindrical need to withstand combination axial compression, bending moment, torsion external pressure. This study contributes parametric investigation for unstiffened ...

Several theories are available in the literature to predict ultimate shear resistance of plate girders, generally known as tension field theories. It is already found out, by many researchers, that prediction majority models mostly over-conservative for non-rigid end post steel girders. So, there a need development accurate finite element models, which could strength better than theoretical mod...

Real-time data acquired under combat conditions will have different types of imperfection; two representative classes of imperfection are vagueness and ambiguity in the data. A motivational example is created in this paper to explore the prototyping of a hybrid processing model that can formally process both vague (fuzzy) and ambiguous (probabilistic) data types. The issue is to integrate the h...

This paper reports a comprehensive experimental and numerical study of the cross-sectional behaviour resistances press-braked S960 ultra-high strength steel (UHSS) channel section structural members. The was conducted on eight different plain sections, comprised material testing, initial local geometric imperfection measurements, as well total 10 stub column tests 20 four-point bending performe...

Obtaining high-fidelity and robust quantum gates is the key for scalable computation, one of promising ways to implement using geometric phases, where influence local noises can be greatly reduced. To obtain gates, we here propose a scheme manipulation by combining phase approach with dynamical correction technique, imperfection control induced X-error suppressed. Moreover, against decoherence ...

Abstract A hot-press molding technique is developed to design and manufacture carbon fiber reinforced polymer (CFRP) X-core sandwich panels that allowed both the composite face sheets its be simultaneously molded together. Compression tests were performed on assess effects of relative density compressive properties failure mode it develops. Analytical models predict panel stiffness strength; a ...

In this study, a hybrid method is proposed to investigate the nonlinear vibrations of pre- and post-buckled rectangular plates for the first time. This is an answer to an existing need to develope a fast and precise numerical model which can handle the nonlinear vibrations of buckled plates under different boundary conditions and plate shapes. The method uses the differential quadrature element...
