Fundamental physical, mechanical, chemical, and thermal properties of construction materials.

Compare axial compression and lateral bulging for standard construction materials under stress.

Select Material

Compressive Stress ($\sigma$)15 MPa

0 MPaAllowable Limit (30 MPa)

Poisson's Ratio ($\nu$):

Measures the lateral expansion of a material when compressed axially. $\nu = -\varepsilon_{lateral} / \varepsilon_{axial}$ .

Deformation Magnified $\times 5,000$

\varepsilon_{axial} = \frac{\sigma}{E}

Axial Strain:

\varepsilon_{ax} = \frac{15}{30000} = 0.000500

0.0500% strain

Lateral Strain (

\varepsilon_{lat} = -\nu \cdot \varepsilon_{ax}

\varepsilon_{lat} = -0.2 \cdot 0.000500 = -0.000100

+0.0100% bulge
