What is Crushing Strength?

n mechanics, compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size (as opposed to tensile strength which withstands loads tending to elongate). In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.

How to Calculate Allowable Crushing Strength of Bolt?

Allowable Crushing Strength of Bolt calculator uses Allowable Crushing Strength of the Bolt Material = Maximum Torque*1/(Number of Bolts*Diameter of Bolt*Thickness of Flange)*(2/Pitch Circle Diameter of Bolts) to calculate the Allowable Crushing Strength of the Bolt Material, Allowable Crushing Strength of Bolt is defined when bolt is strong and the plate is weak in bearing or the weaker plate material may get crushed when the bearing stress in the plate exceeds its bearing strength. Allowable Crushing Strength of the Bolt Material is denoted by f_cb symbol.
