This formula uses 6 Variables
Variables Used
Maximum Stress at Crack Tip - (Measured in Pascal) - Maximum Stress at Crack Tip is the highest stress concentration that occurs at the tip of a crack in a material under load.
Maximum Initial Deflection - (Measured in Meter) - Maximum Initial Deflection is the degree to which a structural element is displaced under a load.
Distance from Neutral Axis to Extreme Point - (Measured in Meter) - Distance from Neutral Axis to Extreme Point is the distance between the neutral axis and the extreme point.
Least Radius of Gyration Column - (Measured in Meter) - Least Radius of Gyration Column is the smallest value of the radius of gyration, it is used for structural calculations.
Direct Stress - (Measured in Pascal) - Direct Stress refers to the internal resistance offered by a material to an external force or load, acting perpendicularly to the cross-sectional area of the material.
Euler Stress - (Measured in Pascal) - Euler stress is the stress in column with curvature due to Euler load.
STEP 1: Convert Input(s) to Base Unit
Maximum Initial Deflection: 300 Millimeter --> 0.3 Meter (Check conversion ​here)
Distance from Neutral Axis to Extreme Point: 10 Millimeter --> 0.01 Meter (Check conversion ​here)
Least Radius of Gyration Column: 47.02 Millimeter --> 0.04702 Meter (Check conversion ​here)
Direct Stress: 8E-06 Megapascal --> 8 Pascal (Check conversion ​here)
Euler Stress: 0.3 Megapascal --> 300000 Pascal (Check conversion ​here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σmax = (((C*c/(rleast^2))/(1-(σ/σE)))+1)*σ --> (((0.3*0.01/(0.04702^2))/(1-(8/300000)))+1)*8
Evaluating ... ...
