Many soft materials respond neither homogeneously nor linearly to an applied shear stress. The authors describe local oscillatory rheology from echography (LORE), a technique based on ultrafast ultrasonic imaging that provides access to spatially resolved viscoelastic moduli under an oscillatory shear. LORE could be used to study a great range of phenomena and systems spanning fundamental and practical interests, such as wall slip, strain hardening, shear thickening, and heterogeneous materials like hardening concrete, foods, and biocomposites.
