There are several mechanical modelling methods for representing pouch cells; this study introduces a modified homogenized model. The model uses mechanical responses of layers from literature to establish an average behavior of a pouch cell. Data is normalized, then unified tension and compression stress-strain curves are gathered. These properties are used to build a homogenized pouch cell model by using a tension and compression plasticity model. A stress state dependent failure model (GISSMO) is utilized to demonstrate the damage of cell. Finally, experimental studies from literature are employed for validation. As a result, the model simulates peak forces of all experimental studies with a very low deviation. Homogenizing pouch cell with the proposed approach eliminates modeling detail without compromising the overall mechanical response of the cell. The model is seen to be suitable for applications that do not require a precise mechanical response, such as a battery module or pack analysis. © 2020 John Wiley & Sons LtdJohn Wiley and Sons Ltd2021Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/13149https://doi.org/10.1002/er.59590363-907XenInternational Journal of Energy Researchinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/13149
