While the internal pressure is low, axial load takes leading roles and prompts tube materials flow in the direction of branch tube that also helps to alleviate the over reduction of wall thickness.
Another is that it may result in great friction resistance between mold and tube, which will hinder the materials into branch.

When machining aerospace monolithic components, most of materials could be removed, resulting in severe deformation of the parts due to the release and redistribution of the blank's original residual stress, together with the action of cutting loads and clamping force.
In the milling process, more than 90% of the materials would be removed which results in its low rigidity.
Computer Simulation The Physical Dimension and Material Properties of the Part.
The removal of the materials is realized by element birth and death technology.

Materials for adsorption Separtation[M].

Rybnicek et al. proposed the binary and ternary blends from three materials including PMMA, PC, and ABS.
Experimental Set-Up and Method Materials, Injection Molding Machine, and Mechanical Measurement Polymer materials were supplied in pellet form.
It is obvious that the increase in melt temperature results in a degradation of PMMA materials in the blend.
This investigation provides a clear understanding for fabricating optical molded elements of materials PMMA/PC blends.

The production of this bioadditive in a biodiesel plant also increases the revenue as raw material comes from biodiesel process production as by-product.This study examines the effects of catalyst concentration and temperature on triacetin production using glycerol from esterification process and acetic acid at volume ratio of 1:3 as raw materials.
With the potential as an additive to increase the octane value of gasoline, triacetin compounds have the potential to be developed, moreover the raw materials used come from biodiesel waste.
Methodology Materials The material used in this study was 2% Fe catalyst with coconut shell carbon carrier.
