Abstract
EN Plastics, or more precisely, polymers, have been utilized as construction materials for numerous decades. The broad range of plastic types results in a vast array of physical properties, consequently yielding a wide spectrum of practical applications. Significant advancements in materials engineering, manufacturing technology, and structural design call for the continuous enhancement of experimental research methods and the exploration of domains that are often regarded as conventional or standardized. The prevailing method for evaluating the mechanical properties of plastics is the static tensile test, which is conducted in accordance with established standards that meticulously delineate the test conditions and specimen preparation methodologies. While static tensile test results furnish valuable information, integrating them with dynamic test results facilitates a more precise evaluation of the structural material under examination. The objective of this study was to conduct a comprehensive investigation of the mechanical properties of film made of low-density polyethylene (LDPE) subjected to static and dynamic loads, thereby enabling the formulation of more comprehensive conclusions about the tested plastic. The methodology entailed conducting experimental static and dynamic tests on samples of recycled LDPE film from this plastic. The experimental results obtained were used to develop a series of mechanical characteristics based on energy relationships. The integration of the outcomes from static tests with impact tests at varying strain rates and impact energies resulted in the identification of several pivotal indices and characteristics. The developed material and structure diagnostic indicators are imperative for future endeavors involving the utilization of LDPE and other unconventional materials as structural materials, particularly in structures designed for controlled mechanical energy dissipation. In summary, a comprehensive understanding of the mechanical properties of materials such as plastics is essential for optimizing their use in specific engineering applications. One critical area where static and dynamic material properties are essential is human safety. Protective measures, including helmets, harnesses, safety belts, and energy-absorbing mats, depend on precise knowledge of material properties.
