Experimental analyses in static regime on the reduced scale model, of the structure of the double bottom

Abstract

The purpose of this paper consists in the experimental analyses in static regime on the reduced scale model of the structure of double bottom. For modelling and stress analysis around relief cutting of a frame floor, the program system with SolidWorks / COSMOS/M finite element was used. In order to validate the results of numerical modelling it was designed an experimental modelling program. This program contained several kinds of experimental modelling: using Resistive Electric Tensometry (RET) and Optical Method (OM) method. A stand was designed to carry out on an experimental checking of the variation of the stress status in the Experimental Model reduced to scale of 1:10.
