Abstract
IN an earlier communication1 we raised the question of the significance of the dissipation coefficient (k) of soft materials, which we measure by compressing cylinders under loads compensated to ensure constant shear stress (S). For materials the firmness (φ) of which is independent of stress, k is defined by an equation of the Nutting type2 where σ is shear strain and t is time.
