Determination of strain and stress distribution on shearwalls by using the speckle photography technique

Simple method for simultaneously measuring the magnitude and direction of 2D in-plane displacement in white-light speckle photography

“…Since the classical work of Burch et al [8,9], SP has achieved significant developments in many application fields, such as engineering and materials science [5,[10][11][12], biomedicine [7,13] and geography and geology [14]. Numerous physical quantities, including in-plane displacement [15,16], in-plane rotation [15,17], out-of-plane displacement [18,19], angular displacement [20], surface tilt [21,22], velocity [23,24], angular velocity [25], vibration [6,17], stress [5,26], strain [27,28], temperature [4,29] and convection [30], can be evaluated with SP. When improved with some modifications in the optical system, SP can also be used in real-time detection [15,31], dynamic course [18,22] and transient process [2,32].…”

Displacements measurement in a building model using the speckle photography technique

“…A major advantage of this method is the relative simplicity of the experimental set-up [2][3][4][5]. It has been applied successfully to study structural elements [6,7] and to measure deformation in buildings in situ [8,9]. Some optical tests, however, due to experimental limitations, cannot be applied directly to real structures because of the large dimensions sometimes involved; consequently the use of reduced scale models becomes necessary.…”
