Maximum Principal Stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

Maximum Principal Stress = (Normal Stress along x Direction+Normal Stress along y Direction)/2+sqrt(((Normal Stress along x Direction-Normal Stress along y Direction)/2)^2+Shear Stress acting in xy Plane^2)
σ_max = (σ_x+σ_y)/2+sqrt(((σ_x-σ_y)/2)^2+ζ_xy^2)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Maximum Principal Stress - (Measured in Pascal) - Maximum principal stress is the maximum stress acting on principal plane due to applied normal load.
Normal Stress along x Direction - (Measured in Pascal) - Normal stress along x direction is the internal resistive force acting longitudinally.
Normal Stress along y Direction - (Measured in Pascal) - Normal stress along y direction is the internal resistive force per unit area acting along y direction.
Shear Stress acting in xy Plane - (Measured in Pascal) - Shear stress acting in xy plane is the shear stress on xy plane.

STEP 1: Convert Input(s) to Base Unit

Normal Stress along x Direction: 80 Megapascal --> 80000000 Pascal (Check conversion here)
Normal Stress along y Direction: 40 Megapascal --> 40000000 Pascal (Check conversion here)
Shear Stress acting in xy Plane: 30 Megapascal --> 30000000 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_max = (σ_x+σ_y)/2+sqrt(((σ_x-σ_y)/2)^2+ζ_xy^2) --> (80000000+40000000)/2+sqrt(((80000000-40000000)/2)^2+30000000^2)

Evaluating ... ...

σ_max = 96055512.7546399

STEP 3: Convert Result to Output's Unit

96055512.7546399 Pascal -->96.0555127546399 Megapascal (Check conversion here)

FINAL ANSWER

96.0555127546399 ≈ 96.05551 Megapascal <-- Maximum Principal Stress
