abstract

The present paper reports on the progress towards the development of a computational workbench infrastructure that implements the Meshless Random Grid (MRG) method for the remote (non contact) measurement of displacement and strain fields in 3D space. The method is applicable to structures bounded by flat surfaces that deform under various mechanical and generalized loading conditions in and out of plane. A brief description of the 3D MRG method is followed by the description of the current prototype of a software workbench developed for the computational implementation of the algorithms involved with the analysis display and export of the experimental results associated with any specific applications of the method.
