A rational approach to estimate reasonable design values of selected joints by using lower tolerance limits

Lower tolerance limits (LTLs) methods was used to estimate design values of furniture joints. To have higher reliability in joint, LTLs were chosen for higher confidence/proportional level. The logic behind phenomena is that if stress on joint exceeds the given LTLs, failure on joints is most likely observed. Therefore, joint sizes were determined to maintain internal stresses on joint below LTLs value corresponding to external load.
