An Experimental Study On Damage Evolution of Unfired Dry Earth Under Compression.

The damage behaviour of unfired dry earth is determined experimentally under compression by means of loading-unloading cyclic tests. The scalar damage parameter is determined and its evolution law is related to the applied strain - $${d (\varepsilon)}$$ . Interpolating functions are determined, permitting to estimate how the damage depends on the deformation process of the considered material. Different aspect-ratios of the specimens are considered.
