Tribological experiments have shown that the coefficient of friction depends on the nature and technology of carbon fiber manufacturing, as well as its heat treatment, which affects both the adhesion properties and the surface roughness of the fiber. Reducing the microrelief of the surface of the ...
Ejection is the most critical phase in the injection moulding process and depends on several variables that can affect and difficult the demoulding process. Some phenomena in the mould, such as shrinkage, adhesion and friction, can lead to higher ejection forces. Friction, deformation and adhesion ...

The friction coefficient f depends on the slip rate V and a state variable ψ: $$f\left( {V,\psi } \right) = a\,{\mathrm{arcsinh}}\,\left( {\frac{V}{{2V_0}}{\mathrm{exp}}\left( {\frac{\psi }{a}} \right)} \right).$$ (3) The state variable ψ evolves according...
Numerous laboratory experiments have found that the coefficient of friction of simulated faults depends both on the instantaneous sliding velocity and on a state variable that represents the previous sliding history. The coefficient of friction is typically given as μ = μ0+a1n( V/V0) + b1n(...

The temperature loss depends on the pipeline’s condition, its burial location, and the amount of insulation installed, if any [5]. Three interrelated steps are taken to design the pipeline network. First, the network geometry needs to be defined by considering the exact path followed by each...
