Stress distribution in disconnected furniture joints

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.
