The stress-strain behaviour of soils as shown in the following figure corresponds to :

• Curve 1 : Loose sand and normally consolidated clay Curve 2 : Loose sand and over consolidated clay
• Curve 1 : Dense sand and normally consolidated clay Curve 2 : Loose sand and over consolidated clay
• Curve 1: Dense sand and over consolidated clay Curve 2: Loose sand and normally consolidated clay
• Curve 1: Loose sand and over consolidated clay Curve 2: Dense sand and normally consolidated clay
