The influence of mortar strength and deformability on brick masonry behaviour under compression and shear is not yet fully understood. Furthermore the necessity of measuring the governing parameters of the constitutive laws of the material requires more and more sophisticated experimental equipment. Optical interferometric techniques allow the measurement of the displacement of points on a surface of a specimen under states of stress with a full-field observation of the inspected surface. This study applies electronic speckle pattern interferometry (ESPI) to the study of brick-mortar interaction under certain stress states.
