## 1 Introduction
Most of the work done with the high strain rate or \"shock\" were mostly alloy or metal structures; the polymer is less well-known in this area6 as it has a less strong impaction strength and can be used in vehicle bumper applications [39; 40]. Moreover. there has not been much research into the shock area, but one piece of research was similar: some of the details focused on the polymers BCC and ECC (edge-centered cubic) lattice structures [41]. Despite the metallic shock impulse study, the BCC and ECC polymer lattices, prepared by an FDM-3D printer, were investigated, using a dynamic shock absorption machine. The dynamic shock absorption machine is a kind of low shock impulse machine that uses a drop weight with a variation of the porosity per centage between 65.4 to 83.5. The BCC and ECC structure had a 12 mm controllable cube cell size, but there were three sizes of the studs' diameters (2.4 mm, 2.8 mm and 3.2 mm). The shock impulse can be used as one of the indicators, and it was concluded that the BCC structure with a stud diameter of 2.8 mm produced the best shock absorption. Regarding the different structures, they might not necessarily behave the same. They were also repeatedly tested with an edge-centered cubic lattice structure, and the smallest stud size showed better shock absorbance [41]. The higher strain rate of a high shock acceleration of several lattice structures has been studied, using a Hopkinson bar [42], and there was a signal response that changed tremendously between the medium and high strain rates when the strain rate was increased [43]. Rankine-Hugoniot is interfacial between low and high pressure that happens under shock [34], which is necessary to be observed by high-speed camera [42]. The study was done with experiments and numerical techniques, concluding that three lattice structures were directly impacted by up to approximately 70 m/s. Also, it seems that all lattice structures suffered a catastrophic failure with the direct impact; the higher the excited velocity shown, the more sign of the convolution curve. The stress showed a positive effect with a relative density, but the energy absorption also had a certain extent correlation with a relative density [42]. In general, transmissibility (T, [-]) refers to the ability of a material to attenuate shock during impulse testing or isolate vibration in response to force vibration. It can be defined as the ratio between the resulting force and the input or excited force. Transmissibility can be viewed as an indicator of efficiency in vibration isolation for all types of materials, including lattice structures. [44]. Although several researchers have investigated the mechanical properties of lattice structures, most of them have been quasi-static. From the literature survey, it appears that no investigations have thus far been conducted concerning the dynamic phenomena of lattice structures in the context of pneumatic shock exciters. Nonetheless, it is of utmost importance to perform preliminary examinations under quasi-static conditions in order to obtain fundamental knowledge. This particular investigation not only offers crucial mechanical properties and collapse modalities for quasi-static assessments, but it also aids in identifying suitable lattice structures for shock impulse utilisation. The findings of this scholarly pursuit are anticipated to considerably enhance the comprehension of lattice structures' shock response behaviour, thereby facilitating more informed decision-making within engineering applications.
