        abstract = {The increasing reliance on plastic enclosures in critical applications such as consumer electronics, automotive, and aerospace underscores the need to assess their long-term durability under adverse conditions [2][9][18][34]. Thermal aging significantly alters the mechanical properties of polymer-based materials, influencing their performance during drop and impact events [3][5][8] [15] [19] [21] [20] [28]. This review synthesizes methodologies for evaluating the drop and impact behavior of thermally aged plastic enclosures, drawing insights from experimental protocols and advanced simulation techniques [6] [7]. Experimental studies reveal that thermal aging induces degradation mechanisms such as oxidation, chain scission, and matrix-fiber interface weakening, leading to reduced tensile strength, impact resistance, and toughness [34] [24] [25]. Standards like ISO 527 and ISO 62:2008 guide the testing of thermally aged specimens, highlighting the effects of controlled temperature and humidity exposure [37] [40] [26] [29]. Techniques such as tensile, flexural, and drop-weight impact tests are integral for quantifying changes in material properties, while accelerated aging protocols mimic real-world degradation within shorter timeframes [30] [16] [38] [20] [28] [29]. Simulation-based approaches complement experimental findings by providing predictive insights into material performance [44] [48]. Finite element analysis (FEA) tools, enable the modeling of impact scenarios and material degradation. Material models that incorporate strain rate sensitivity and temperature-dependent properties improve simulation accuracy, aligning predictions with experimental data [11][30][31]. Despite advances in methodology, challenges remain in standardizing protocols and bridging laboratory results with field performance. Emerging trends, such as machine learning-assisted simulations and sustainability-focused material recycling, offer promising directions for future research.
This review highlights the interplay of experimental and computational methodologies in understanding the impact resistance of thermally aged plastic enclosures, providing a comprehensive framework for researchers and industry professionals. It calls for the integration of advanced techniques and standardized protocols to ensure the reliability and sustainability of polymeric materials in demanding applications [2][9][32][33] [41] [51].},
