7. Conclusions

7.1 General expression of shear strength

For stability calculations of geotechnical structures, the shear strength of soils is classically represented by the following relationship between normal and tangential stresses on the failure surface:

τ = c + σ tan ϕ

with :

τ
 : 
shear strength (tangential stress limit)
σ
 : 
normal stress
c
 : 
cohesion
