This paper deals with the experimental testing of the basic crash elements which are made of PA6 with short carbon fiber reinforcement by additive technology. Additive technologies allow the production of very complex, thin-walled and hollow shapes, which can be used to tune the desired characteristics of the deformation member. The variable size of the deceleration, the length of the deformed part and the total amount of energy absorbed can be controlled by suitable geometry. The initial impact peaks can be reduced by gradually changing the geometry. Experimental testing of the basic crash elements was performed on several specimens and average values are used in this paper. The maximal and the average deceleration and total energy absorbed are primarily monitored. The obtained data will be used for validation of material properties in Crash-Pam software. Usage of a validated material model, larger and more complex deformation members will be proposed, e.g. for the racing car Formula SAE.

The goal of this paper is to introduce the proposed parameterized sub-systems of HVAC piping system (HVAC = heating, ventilation, air conditioning). Parameterized 3D models of piping sub-systems and supports of piping system were created. Using control parameters we can control not only the size of pipes and supports, but with logical parameters (0/1) and conditions, we can change the sub-system type, or show and hide individual parts of the sub-system. This spectrum of parameterized models enables quick and efficient design of HVAC piping system.

“…The advantages of adhesive bonds are that they have not Heat-affected zone (such as welding, [8], [9], [10], [20]) and they do not need to drill holes (stress concentrators) as bolted joints and riveted joints [6], [7]. Gluing is also suitable for printed composite parts [11], [12], [13].…”

The paper deals with the determination of cohesive parameters of adhesive Scotch-Weld DP490 3M. Mode I of cohesive damage were examined. Experimental testing was performed on the test specimens to determine the mechanical properties of the adhesive. The results of the experimental testing were compared with the numerical simulation and analytical solution of the same test. The cohesive parameters of the adhesive were obtained from the numerical simulation. Cohesive parameters of adhesive can be used to design real adhesive bond.
