According to the method, the allowable stress value is the ratio value of yield strength to a safety factor N; the safety factor N is the sum of the product and a basic safety factor n of the casting material, the product is of the increase coefficient k of the safety factor of the ...
The earth pressure against the retaining piles with interval consists of two parts: direct and indirect earth pressure. The calculation principle of earth pressure using principal stress arching is proposed.关键词: retaining pile earth pressure soil arching minor principal stress arch ...
I think I also need to apply a fatigue stress concentration factor to this von Mises stress. Shigley and other references report fatigue thread stress concentration factors of Kf=2-5+. For now, I'm using kf=3. I'm unclear as to whether kf applies to the von Mises stress or if it ...
In order to make use of the modified method for calculating tooth root stress for gear dimensioning, it has to be correlated and validated with an appropriate determination of the permissible bending stress. Until then, it will not be possible to calculate safety factors for a given tooth geomet...
amost fluids in HVAC applications can be treated as newtonian,where the rate of deformation is directly proportionaln to the shearing stress 多数流体在HVAC应用可以对待牛顿,变形的率直接地是proportionaln到抗剪应力的地方[translate] a但是现在它不在原来的地方了 But now it not in original place[transla...
In the laboratory, the damage tolerance of a material is typically tested using specialized equipment such as tensile or compression machines. These machines apply controlled amounts of stress or strain to the material and measure its response. Other tests, such as fatigue tests, can also be used...

Take the minimum tensile strength in psi of the ASTM grade, multiplied by the stress area of the diameter. This formula will give you the ultimate tensile strength of that size and grade of bolt. Example: What is the ultimate tensile strength of a 3/4″ diameter F1554 Grade 36 rod? Thi...
The stress will then be an "allowable stress." The force will be the "force weight" of 7 kg. To make a long story short, your allowable stress = 60% X Yield Stress / Impact Factor. The Yield Stress will be based on the grade of steel. Let me know if you need help with this....
