The bending rigidity and the bending and reversing strength of the driving shaft of the one grade straight and Cylinder form garewheel decelerator are different when the direction of the pulling power from the V form ribbon to the driving shaft changes in the drive device of ribbon type conveying machine.

Theoretical analysis of the torsional strength of pretressed concrete member subjected to complex loading;

Accurate calculations for the purpose of the structural design and functional analysis require precise knowledge of the torsional strength of each concrete structural member.

Study of the torsion strength and material toughness criteria of drill pipe tool joint;

The detecting system of stress wave velocity for laminated veneer lumber bending strength based on single chip;

Analysis on bending strength of PcBN composite;

Effect of pore-forming agents content on bending strength of SiC/Al composites;

Application of artificial neural network method in prediction of bend strength of welded joint;

In the prouduction of (WC15Ni ) non-magnetic Cemented Carbide we can improve the bend strength by choosing the high quality WC which has narrower range of particle size distribution and adding moderate Cr3C2.

It is showed from the result that with an appropriate amount of addition of above alloy powder the hardness and bend strength of copper alloy are both raised: when addition being as 1.
