Year	1
Semester	S1
ECTS Credits	6
Workload	OT(15H)
Scientific area	Engenharia Civil
Entry requirements	According to the law and the Course criteria
Learning outcomes	1 – Domain in engineering of soil and its behavior - states of stress and strain; 2 - Domain in stress-strain paths and invariants; 3 – Domain in overconsolidated samples behavior – Hvorslev surface; 4 – Domain of mechanical behavior of soils before failure; 5 – Understanding the critical state and the Roscoe surface 6 – Domain of Laboratory tests in soils
Syllabus	1 - Engineering of soil and its behavior – Stresses and strains in soils (physical relationships for soils; the significance of effective stress; increments of stress and strain); 2 - Stress-strain paths and invariants (stress paths; invariants of stress; strain paths; volumetric strains); 3 - Critical state line and the Roscoe surface (drained and undrained tests and planes; the Roscoe surface and the shape; state boundary surface); 4 - Behavior of overconsolidated samples – Hvorslev surface (drained tests; Hvorslev surface; complete state boundary surface); 5 - Behavior of soils before failure (elastic and plastic deformations; calculations of elastic strains; plasticity for soils; Cam-clay) 6 - Laboratory tests on soils (tests for soil classification, triaxial apparatus; oedometer, direct shear box; simple shear apparatus).
