Sekundarni naslov:	Failure analysis of Trimo sandwich panels due to face wrinkling
Sekundarni povzetek:	This work deals with numerical simulation of experimental tests on Trimo sandwich panels. Panels are made of foam core and lightly profiled steel faces. The experiments were performed at the Slovenian National Building and Civil Engineering Institute. They were designed to evaluate the failure force (load) due to wrinkling of the steel face. The wrinkling is a consequence of buckling due to delamination between the core and the compressed face. The setup of the experimental tests and some experimental results are briefly presented. Numerical simulations are based on the nonlinear finite element method and commercial code ABAQUS. The finite elements chosen for simulation of the problem are presented; especially the cohesive elements that were used to model connection between the faces and the core. Numerical model was prepared by exploiting experimental results on panel called FTV 60. First a basic model was chosen. Then several poorly known parameters of basic model were varied in order to estimate their values and their influence on numerical results. In such a way the basic model was improved and an »optimal« model was finally obtained. It was found out that good knowledge of the shear strength between the facings and the core, as well as physical properties of the core material, are very important. Once the model was chosen, the numerical simulations were performed also on panels FTV 120 and FTV 200. All numerical results are within 10% agreement with the experimental results. That is very good, since not all material data has been available. Also, the measured results vary considerably.
