“…A split Hopkinson pressure bar laboratory set-up presented in (Figure 15) was used to perform these studies. The principle of operation of the SHPB is well known and it was discussed in numerous works [54][55][56]. The SHPB apparatus is generally used to perform the identification of mechanical properties of materials under a high-strain rate.…”

The main aim of the paper is to evaluate the mechanical behavior or lattice specimens subjected to quasi-static and dynamic compression tests. Both regular and three different variants of SS 316L lattice structures with gradually changed topologies (discrete, increase and decrease) have been successfully designed and additively manufactured with the use of the selective laser melting technique. The fabricated structures were subjected to geometrical quality control, microstructure analysis, phase characterization and compression tests under quasi-static and dynamic loading conditions. The mismatch between dimensions in the designed and produced lattices was noticed. It generally results from the adopted technique of the manufacturing process. The microstructure and phase composition were in good agreement with typical ones after the additive manufacturing of stainless steel. Moreover, the relationship between the structure relative density and its energy absorption capacity has been defined. The value of the maximum deformation energy depends on the adopted gradient topology and reaches the highest value for a gradually decreased topology, which also indicates the highest relative density. However, the highest rate of densification was observed for a gradually increasing topology. In addition, the results show that the gradient topology of the lattice structure affects the global deformation under the loading. Both, static and dynamic loading resulted in both barrel- and waisted-shaped deformation for lattices with an increasing and a decreasing gradient, respectively. Lattice specimens with a gradually changed topology indicate specific mechanical properties, which make them attractive in terms of energy absorption applications.

Pressure sensing is not a new concept and can be applied by using different transduction mechanisms and manufacturing techniques, including printed electronics approaches. However, very limited efforts have been taken to realise pressure sensors fully using additive manufacturing techniques, especially for personalised guide prosthetics in biomedical applications. In this work, we present a novel, fully printed piezoresistive pressure sensor, which was realised by using Aerosol Jet® Printing (AJP) and Screen Printing. AJ®P was specifically chosen to print silver interconnects on a selective laser sintered (SLS) polyamide board as a customised substrate, while piezoresistive electrodes were manually screen-printed on the top of the interconnects as the sensing layer. The sensor was electromechanically tested, and its response was registered upon the application of given signals, in terms of sensitivity, hysteresis, reproducibility, and time drift. When applying a ramping pressure, the sensor showed two different sensitive regions: (i) a highly sensitive region in the range of 0 to 0.12 MPa with an average sensitivity of 106 Ω/MPa and a low sensitive zone within 0.12 to 1.25 MPa with an average sensitivity of 7.6 Ω/MPa with some indeterminate overlapping regions. Hysteresis was negligible and an electrical resistance deviation of about 14% was observed in time drift experiments. Such performances will satisfy the demands of our application in the biomedical field as a smart prosthetics guide.

“…16,17 Furthermore, the rubberlike materials exhibit totally different response characterics at quasi-static (10 À3 s À1 ) and high-rate loadings (10 2 -10 3 s À1 ). 1,2,7,11,13 It is necessary to obtain the mechnical respnses of rubber-like material at intermediate strain rates to evaluate their rate dependence more accurately and comprehensively. On the other hand, traditional quasi-static testing method and split Hopkonson bar technique can not be simply extended to achieve the intermediate strain-rate testing conditions.…”

The uniaxial tensile stressstrain responses of carbon black filled rubbers were experimentally investigated at various strain rates of 0.001, 0.05, 2.5 and 400 s À1 . A conventional hydraulically driven material testing system, an intermediate strain-rate testing system and a split-Hopkinson tension bar were respectively utilized to carry out the monotonic tensile loadings at quasi-static, intermediate and high strain rates. A complete experimental strategy for intermediate strainrate testing of rubber-like materials with low modulus and low strength was proposed including constant strain-rate loading, sample clamping and dynamic force measuring methods. The experimentally obtained engineering stressstrain results show that the tensile properties of carbon black filled rubbers are highly nonlinear and rate-dependent. A visco-hyperelastic constitutive model based on the modified eight-chain model parallel with three linear Maxwell elements was developed to describe the tensile responses of carbon black filled rubbers. Especially, the relationship between the number of Maxwell elements used in the model and the tested strain rate range was discussed.
