Applications of speckle interferometry to civil engineering in Cuba

摘要

Speckle interferometry has been introduced in Civil Engineering at CUJAE in 1988 as a useful technique in research work. This paper describes some applications of speckle interferometry in civil engineering. Speckle photography has been utilized to study deformation in shearwalls, and also studding of behavior building model under concentrate loading. Displacements were numerically calculated using a finite element method. Electronic Speckle Pattern Interferometry (ESPI) has been used for the measurement of the Young's modulus in mortars and concrete. Obtained values of the Young's modulus are in good agreement with reported for mortars or measured by a static compressive technique for concrete.
