The objective of investigations was to determine rigidity and strength of temporary joints applied in cabinet furniture. In particular, the authors intended to determine the distribution of ordinary stresses in wood, metal and plastic connections of temporary joints and in parts of boards in direct contact with these fastenings. The performed laboratory investigations and numerical calculations showed that trapezoid temporary joints with metal construction were characterised by the most advantageous rigidity-strength properties, while wood dowels in these joints were found to play a significant role supporting their strength.

The presented study is of theoretical nature aiming to perform a numerical analysis of structural strength of skeleton furniture subjected to real useful loads. The objective of the performed investigations was to determine the state and distribution of stresses in the angle joint of a spatial structure of skeleton furniture. Experiments were carried out on dowel and tenon and mortise joints, which belong to the group of flat angle joints. The performed experiments allowed to develop a numerical model of a skeleton construction which was later used to perform calculations determining: reduced stresses according to the von Mises theory, tangential stresses in glue lines of dowel and tenon and mortise joints and tangential stresses in the wood of dowel joints. The results presented in this study are of cognitive nature. They determine values of stresses in joints of the loaded furniture piece and identify places with the greatest effort.

В статье рассматривается склееный параллельно волокнам стыковыми плоскостями деревянный щит составленный из трех элементов изготовленных из одного и того же вида древесины. Представляющий собой симметрическую механическую систему щит подвергался сжиму вызывающему срез шововых поперечных разрезов. Рассматривая древесину как упругое тело, были определены составные напряжения в щите при использовании теории упругости анизотропного тела, а также функции напряжений содержащей тригонометрический ряд. В связи с малой толщиной клеевого шова было оставлено вне учета его влияние на деформации и напряжения в щите. Исчисляли аначения срезывающих и нормальных напряжений в клеевом шове для щитов изготовленных из трех видов древесины: сосновой, буковой и дубовой, а для сравнения также из изотропного материала. Учитывали также изменчивую геометрию щита связаннцю с различными ширинами его боковых частей и его разную высоту. Графически представлены распределения напряжений в клеевом шове для отдельных материально-геометрических случаев. Труд заканчивается анализом результатов пополненным выводами.

Mechanisms of load capacity and stability decline. Article deals with failures of constructions with considerations of static work states. Analysis of bent beams and compressed columns was made, as most important elements of wooden structural works. Most common structural members failures causes were described, as design and manufacturing errors as well as local weakening caused by wood structural defects. Because of subject challenging, it is purposeful to take a detailed look into the problem, in aim to determine cracks propagation in dependence on type and placement of the defect.

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.
