heal.abstract	The subject thesis had as scope the finite element modeling of sandwich material specimens, used in tests conducted for the characterizations of the shear properties of the core, in order to investigate which are the phenomena that occur during their loading. Models for 3-point bending and shear stress-calculation tests were developed in Abaqus based on the testing standards ISO 14125 and ASTM C273 and the materials were modeled, so as to obtain a response similar to the one observed through the actual experiments. The main material properties and the geometry of the model where obtained by previous research on this topic and were used as a starting point in order to model all the linear elastic and damage properties of the materials. Various modeling techniques, such as modeling of the damage response and cohesive zone modeling were introduced in an effort to capture the response of the specimens during the test.	en
