It is assumed that the equilibrium state exists in the SHPB test (Gray 1985b). This means that the forces on both ends of the specimen are equal with F1(t) = F2(t), which gives εi(t) + εr(t) = εt(t). In this sense, the measured values of εi(t), εr(t) and εt...
Yes, rotational motion can reduce static friction if the object is rotating at a constant speed. This is because the force of static friction only acts on an object when it is at rest or when it is trying to start moving. Once an object is in motion, the force of static friction is ...
This section describes the implementation of the quasi-static mooring solver. Moorings are defined as the lines that hold in position a vessel or any kind of floating object. More precisely, this implementation is focused on continuous ropes and wires. The shape of this kind of lines, hanging ...
An experimental testing program and analytical modeling were conducted to evaluate the structural performance at the service and ultimate limit states. Thirteen full-scale bridge deck specimens were constructed and tested under static and fatigue loading. The fatigue loading was applied up to two ...
Using a quasi-static approximation to the tether dynamics, the equilibrium states of a tether cable were determined during straight motion and at the constant speed of the seabed walking robot. The simulation is extended for various input parameters. The basic input parameters to the solution of ...
Solar photovoltaic parameter estimation using an improved equilibrium optimizer. Sol. Energy 2020, 209, 694–708. [Google Scholar] [CrossRef] Houssein, E.H.; Zaki, G.N.; Diab, A.A.Z.; Younis, E.M.G. An efficient Manta Ray Foraging Optimization algorithm for parameter extraction of ...
In this paper, starting from the model of a double-layered pipe developed in [20], and with the aim of obtaining a closed-form description of the static behavior, the nonlinear equilibrium equations in terms of kinematic descriptors are addressed through a specific perturbation scheme. As an es...
Equilibrium between input and output power occurs at the new frequency 𝑓=𝑓0+Δ𝑓f=f0+Δf as shown. According to the slope of the power-frequency characteristic given by Equation (5), the frequency change (in Hz) is shown in the equation below. Δ𝑓=−Δ𝑃G⋅𝑅=−Δ...
