First, we created labeled friction coefficient image datasets representing asphalt concrete surfaces under four moisture conditions. Second, we used a diffusion model to enhance the dataset, increasing sample diversity. Finally, we trained a TNT model on the extended dataset to recognize friction ...
In the presence of a pressurized concrete–concrete interface, the sliding motions are initiated suddenly in a stick-slip mode as compared to wet and dry interfaces. Moreover, the high sliding velocity at the initiation of motion also promotes a reduction in friction coefficient, as explained by...
Concrete rotating drum by friction wheels hopper and elevator for sand and gravel characterized presenting a loading hopper at least fixed with a mouth at such a height that allows the material charge with ordinary means or shovel unloading a drum ring provided with fins or substantially radial ...
The retarding force that stops the motion of the object is known as a frictional force which is equal to the product of the coefficient of friction between the surface and object and the normal reaction force that is applied by the surface on the objectAnswer and...

Löf and Hawley (1948) reported the correlation for heat transfer coefficient for bed of gravel under normal voids and mentioned that large variation of heat transfer coefficient may be expected with change of bed voids and shape of material elements. Standish and Drinkwater (1970) emphasized that...
As concrete contains large size aggregates that may pose difficulty to small scale test models, the pseudo-rock samples are prepared using cement, PoP, sand and water [12], [13]. Literature studies and field data have indicated that, load–displacement behaviour of rock sockets is non-linear...
From back-calculation of the lateral earth pressure coefficient by using experimental results and statistical analysis, the K value depends on the initial stress condition, the relative density of sand, internal friction angle of sand, the skin friction angle between sand and pile materials, and nor...
The following Equation (9) was used to calculate the coefficient of volume compressibility (mv) of the mixtures based on Figure 15. 𝑚𝑣=Δ𝑒1+𝑒01𝜎′𝑣mv=Δe1+e01σ′v (9) where 𝑒0e0 and Δ𝑒Δe are the initial void ratio and void ratio changes, respectively, ...
Constructing offshore wind turbines on artificial islands is considered a viable option, but negative skin friction (NSF) is a significant adverse factor that cannot be ignored. The NSF adversely affects the bearing capacity of pile foundations. Currentl
