About this test
Enter σ3, deviator stress and pore pressure at failure.
How it's calculated
- p = (σ1 + σ3)/2, q = (σ1 − σ3)/2
- sinφ = tanα, c = a/cosφ
Results are calculated from the values you enter using standard formulas. Download the PDF to keep a record. For certified testing, design or construction, talk to our engineers.
