    Ballistic impact analysis of multilayered armour system using finite element analysis
    (Elsevier, 2024) Doddamani, S.; Kulkarni, S.M.; Joladarashi, S.; Mohan Kumar, T.S.; Gurjar, A.K.
    The application of finite element analysis (FEA) to the ballistic impact analysis of polymer composites used in armor is covered in this chapter. This study aims to assess polymer composite armor materials' performance and establish their resistance to high-velocity projectile impacts. The use of FEA enables accurate simulations of the impact process that take into consideration the properties of the materials, the geometry of the projectile and the armor panel, and the impact conditions. The investigation' findings shed important light on how the polymer composite armor responds to impacts and its capacity to absorb and dissipate impact energy. For the development of cutting-edge armor materials and the multiscale modeling method of armor design, this information is essential. The chapter ends with recommendations for further research as well as a discussion of the difficulties and restrictions of employing FEA for ballistic impact analysis. © 2024 Elsevier Ltd.

    Investigation of fracture toughness analysis of polymer composites using finite element analysis
    (Elsevier, 2024) Doddamani, S.; Begum, Y.; Bharath, K.N.; Rajesh, A.M.; Mohamed, K.K.
    This chapter includes a study on using finite element analysis (FEA) to investigate the fracture toughness of polymer composites. This study’s objective is to assess polymer composites' fracture toughness. By considering the material properties and stress distributions, multiscale modeling approaches in FEA enable a thorough assessment of the material behavior under various loading circumstances. The analysis’s findings shed important light on the polymer composites' fracture toughness. The chapter ends with recommendations for further research and a review of the benefits and drawbacks of employing multiscale modeling and FEA techniques to analyze fracture toughness in polymer composites. The results of this work have significant ramifications for polymer composite structure design and optimization, particularly in applications requiring high fracture toughness. © 2024 Elsevier Ltd.
