Abstract - The accurate simulation and analysis of nonlinear dynamic problems across various scientific disciplines are essential for understanding complex physical phenomena. Time integration methods play a crucial role in numerically solving these problems, providing numerical approximations to the time-evolution of systems governed by ordinary or partial differential equations. This paper presents a comprehensive exploration of time integration methods tailored for addressing nonlinear dynamic problems encountered in diverse fields such as physics, engineering, and computational sciences. The review encompasses a detailed analysis of fundamental time integration techniques, including explicit and implicit schemes, highlighting their respective advantages and limitations in handling nonlinearities. Furthermore, it examines advanced time integration approaches specifically designed to tackle the challenges posed by nonlinear systems. This includes discussions on adaptive time-stepping methods, geometric and symplectic integrators, and other specialized techniques aimed at enhancing accuracy and stability while mitigating computational costs. Through illustrative examples and comparative analyses, this paper evaluates the performance of various time integration methods in addressing nonlinear dynamic problems. It delineates the significance of these methods in accurately capturing system behavior and elucidates their implications for practical applications. Additionally, this review identifies current challenges and outlines prospective directions for further advancements in time integration methodologies tailored to the intricacies of nonlinear dynamic systems. This comprehensive review aims to provide researchers, practitioners, and computational scientists with valuable insights into selecting and implementing appropriate time integration methods for effectively addressing nonlinear dynamic problems across diverse scientific domains.
