🏗️

Input Material Parameters

Enter tensile force, cross-sectional area, or strain ratio.

Calculated Mechanical Stress (σ)

300.00 MPa
💡

Hooke's Law of Elasticity

In the elastic deformation regime, stress is directly proportional to strain: σ = E × ε, where E is Young's Modulus (1 GPa = 1000 MPa = 10⁹ N/m²).

Calculation Methodology & Details

📐

Formula

Normal Stress: σ = F / A Poisson's Ratio: ν = -ε_transverse / ε_axial Young's & Shear Relation: E = 2G(1 + ν) Von Mises Stress: σ_vm = √[½((σ₁-σ₂)² + (σ₂-σ₃)² + (σ₃-σ₁)²)]

Applies continuum mechanical stress tensors, Mohr's circle transformation, Euler column buckling, and Brinell/Rockwell hardness conversions.

📢

Important Disclaimer

Calculations assume linear isotropic elastic solid properties under static loading unless plastic yield limits or fatigue S-N curves are selected.

FAQ

What is Poisson's ratio (ν)?
Poisson's ratio is the negative ratio of transverse contraction strain to longitudinal extension strain. Most structural engineering metals have ν between 0.27 and 0.33 (incompressible materials ν = 0.50).
What is thin-walled pressure vessel hoop stress?
Hoop (circumferential) stress σ_h = (P × d) / (2t). It acts tangentially along the cylinder wall and is exactly twice as large as axial longitudinal stress σ_a = (P × d) / (4t).
How is Euler column buckling load calculated?
Critical buckling load P_cr = (π² × E × I) / (K × L)², where E is Young's modulus, I is area moment of inertia, L is column length, and K is end-fixity factor (pinned-pinned K=1, fixed-fixed K=0.5).
