This paper highlights its deficiencies when the designer cannot obtain any expert recommendations or guidelines from the computer’s program. The advantages and disadvantages are set out, and any potential benefits gained from using an intelligent decision support system for plastic products’ design are introduced. The proposed decision support system contains human cognition within the field of design knowledge and special domain knowledge expertise regarding plastics supported by design methodology called ‘Design for Manufacturing’ (DFM).

This paper deals with the manipulability problem of a novel 3 DOF MR compatible haptic mechanism, considering limited space and its visualisation. Choosing a suitable driving system is one of the crucial design attributes for quality force transmission in haptic interfaces. This paper introduces certain adaptations, which have been done to enable the MR compatibility of a cable drive driven by an electric motor. It also presents the theoretical modelling of a cable drive for a 3 DOF MR compatible haptic mechanism, focusing on the hysteretic behaviour of polymeric cables.

The effect of residual stress on the fatigue crack propagation was analysed for a loading regime close to threshold stress intensity factor range. By varying the stress ratio and the stress intensity factor range, different shapes of crack front can be realized. From the shape of the crack front and the variation of the crack front, the resulting residual stresses and local stress intensity can be determined by means of finite element modelling. It is possible to estimate the limit values of the stress intensity factor induced by the residual stresses at selected regions.

This paper presents analytical travel time models for the computation of travel time for automated warehouses with the aisle transferring S/R machine. A simulation model of multi-aisle AS/RS has been developed to compare the performances of the proposed analytical travel time models. The analyses show that regarding all examined types of multi-aisle AS/RS, the results of proposed analytical travel time models correlate with the results of simulation models of multi-aisle AS/RS.

The paper describes an experimental investigation of regular open-cell cellular structures. Cellular structures with circular and quadratic cells have been manufactured with the laser sintered rapid prototyping technique using polyamide PA-12 as the base material. An advanced approach for Poisson’s ratio evaluation is proposed, which is based on the three-dimensional laser scanning technique. The energy absorption characteristics show advantageous performance of cellular structures with circular cells in comparison to the quadratic cells.
