Experimental and FEM Investigation of Cob Walls under Compression

Figure 9

Compressive stress-strain diagrams for the specimen tested at about 0.025 MPa/min (Wall A) and comparison with other tested specimens (about 0.077 MPa/min). The reported vertical compression strains are obtained by averaging the displacements measured by the two vertical LVDTs, respectively. Post-peak behaviour (dotted lines) can be considered as completely reliable since test was force-controlled.
