In the cutting process, the defects and breakage of the SiC particles themselves will lead to the formation of micro-cracks. The growth of micro-cracks in the shearing area is an important factor in the generation of chips. By comparing the simulation results with the experimental results, the...
The aim of the paper is the development of a third-order theory for laminated composite plates that is able to accurately investigate their bending behavior in terms of displacements and stresses. The starting point is given by the corresponding Reddy’s
The oxygen atom of furan has a lone pair of electrons that can coordinate with the metal center of the catalyst, in this case, titanium. Furan binds to the active site of titanium through a coordinate bond, forming a furan–titanium complex. This binding blocks the catalyst’s active sites...
