What was discovered
A mathematical model describing how brittle materials (concrete, soil, rock) respond to shear and normal stress, combining Coulomb's internal-friction criterion with Mohr's graphical stress representation.
What it led to
- reference criterion in geotechnics for the shear strength of soils and rocks
- calculation of failure load and fracture angle in structural engineering
- basis for foundation and slope design
- integration into modern numerical soil mechanics models
