51 Figure Q4.2: v against ln( σ ' v ) O – A: “elastic” reloading A: maximum previous preconsolidation pressure (200 kPa); sample moves onto normal (first) compression line A – B: normal (first) compression: “elastic” plus plastic (irrecoverable) deformation. Plastic deformation is due to particle slip B – C: “elastic” unloading “Elastic” compression and swelling take place entirely as a result of particle distortion, i.e. without relative slippage of the soil particles. During normal (first) compression, plastic
