To modify the incremental strain method used to evaluate non-uniform residual stress, a finite element analysis (FEA) of the reference model used to describe a hole-drilling test was conducted. The calibration factors for the x and y directions were obtained from the analysis and then their differences were compared under various loading conditions. A hole-drilling test using a steel plate as the reference specimen was introduced, and under the pure bending load, strain relaxation was measured at each hole-drilling step to determine the calibration factors. Although the calibration factors in the x and y directions varied with the boundary conditions used in the FEA, their differences were reduced to zero for all depths when the prescribed loads as the boundary conditions in the x and y directions became the same. In addition, it was analytically and experimentally confirmed that the calibration factors did not vary with the direction. Accordingly, by making the calibration factors equal in the x and y directions in the modified equation for the incremental strain method, no singularity is produced in the stress calculations.

The objective of the paper is the parametrization and the finite element analysis of mechanical pro­per­ties of a through dovetail joint made with the use of a specific procedure by a 3-axis CNC machine. This corner joint was used for the simulation of the bending load of the joint in the angle plane – by compression, i.e. by pressing the joint together. The deformation fields, the stress distribution, the stiffness and the bending moment of the joints were evaluated. The finite element system ANSYS was used to create two parametric numerical models of the joint. The first one represents an ideal­ly stiff joint – both joint parts have been glued together. The second model includes the contact between the joined parts. This numerical model was used to monitor the response of the joint stiffness to the change of the static friction coefficient. The results of both models were compared both with each other and with similar analyses conducted within the research into ready-to-assemble furniture joints. The results can be employed in the designing of more complex furniture products with higher demands concerning stiffness characteristics, such as furniture for sitting. However, this assumption depends on the correction of the created parametric models by experimental testing.

Ab s t r act Hybrid Rubberized Composite Slabs (HRCS) is an innovative material which has been developed for highway barriers in bridge construction to avoid vehicle accidents and thereby reducing the risk to public. A three dimensional hybrid rubberized composite slab model (HRCS) was created using Finite element Analysis Software ANSYS and was validated by previous experimental research works on concrete with crumb rubber. Finite element simulations were performed to examine the effect of replacing 0-20% of fine aggregates with crumb rubber. The load-displacement behavior was analyzed for the plain and hybrid rubberized composite slabs under static bending loads. From the results, it was found that, the displacement decrease significantly with increase in the amount of fine crumb rubber replacement. The static bending load decreases as the percentage of replacement of fine crumb rubber increases. Aggregate replacement with crumb rubber in concrete decreases its strength under static bending load. As confirmed by experimental results, FEA can effectively simulate the behaviour of HRCS when the proper numerical model is adopted.
