''I will present an experimental study of the plastic response of a model amorphous material: a packing of glass spheres uniaxially compressed. Our experiment allows us to explore several scales both spatially and in term of strain increment. Two different behaviors can be identified and characterized: an intermittent plastic flow which can be understood in the framework of current theories of the plasticity of amorphous materials, and a slow, large-scale behavior which undergoes a symmetry breaking initiating the formation of the shear band.''
