Stifness modelling of semi-rigid furniture joint with eccentric connector. The aim of the presented study was to model semi-rigid furniture joint with eccentric connector. In the range of investigations was modeling particleboards in three cases, one layer, three layer and five layer. Furniture corner joint with eccentric connector was model as Hettich Rastex 15, with twister DU 644 screw-in dowel and socket number 100. Particleboard was modelled as linear orthotropic material. For modelling SolidWorks Simulation 2011 package was used. Results shown that, increasing the number of layers increases the accuracy of simulation, and the model brings to the real density profile.
