In the presented paper the local instabilities occurring in compression test of perforated thin-walled bars of low slenderness are observed using digital image correlation system ARAMIS. The tested samples slenderness is so low, that from theoretical point of view we are dealing with compression tests of some perforated shells. The samples are made from typical low carbon steel, which has to be treated as elasto-plastic material. Because of that, the final geometry of the sample (after unloading) is also analysed giving a good data for calibration of the theory of elasto-plasticity for large deformations. In analysed cases the total strain values are not exceptionally large, while local rotation (and permanent deformations) have significant values.

Correlation System

Sandwich panels with textile-reinforced cement (TRC) faces merge both structural and insulating performance into one lightweight construction element. To design with sandwich panels, predictive numerical models need to be thoroughly validated, in order to use them with high confidence and reliability. Numerical bending models established in literature have been validated by means of local displacement measurements, but are missing a full surface strain validation. Therefore, four-point bending tests monitored by a digital image correlation system were compared with a numerical bending model, leading to a thorough validation of that numerical model. Monitoring with a digital image correlation (DIC) system gave a highly detailed image of behaviour during bending and the strains in the different materials of the sandwich panel. The measured strains validated the numerical model predictions of, amongst others, the multiple cracking of the TRC tensile face and the shear deformation of the core.

Umbilical Cable

Focusing on the integrity of umbilical cable components during the laying operation, particularly on hoses integrity, this paper assesses displacement fields on umbilical cable cross-sections by means of a special crushing test setup. Using a high resolution Digital Image Correlation system (DIC), experiments with two umbilical cables are carried out in a 250 kN mechanical tests rig. Besides measuring the components displacements, applied crushing forces and shoes displacements are acquired. The experimental samples are taken from two HCR-hoses umbilical cables, which have been cases of study of a finite element analysis methodology, recently proposed and presented in OMAE2015, [12]. Experimental analysis and a theoretical-experimental correlation are presented, for both umbilical cables.
