Wyznaczanie zmian stałych sprężystości materiału występujących na grubości modelu gipsowego

The paper is dealing with experimental determination of elastic constants E and v in a plaster plate produced by pouring the liquid plaster paste over a horizontal glass panel. The structure of such a plate is non-homogeneous. On the basis of strain measurements of a plaster beam cut out of such a plate and subjected to bending, the variation of elastic moduli E and v across the thickness of the plaster plate can be determined.
