About this test
Enter the normal load and peak shear load of each specimen to get c and φ with the failure envelope chart.
How it's calculated
- σ = N/A, τ = T/A
- Best-fit line τ = c + σ tanφ
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.
