    Extension of Ordinary State-Based Peridynamic Model for Nonlinear Analysis

    Mengnan Zhang1,*, Fucheng Tian1

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.26, No.4, pp. 1-1, 2023, DOI:10.32604/icces.2023.09593

    Abstract Peridynamic is a nonlocal theory that uses integral forms of governing equations, making it suitable for describing objects with discontinuous states such as cracks. After more than two decades of development, peridynamic has been effectively applied to numerous solid mechanics studies. However, in the field of ordinary state-based peridynamic modeling nonlinear deformation, a more comprehensive model that can establish a general connection with continuum mechanics and allow for the selection of different influence functions is still lacking. As a consequence, a further extension to existing models is promising, and it represents a substantial addition to… More >

    An Acceleration Scheme for the Phase Field Fatigue Fracture Simulation with a Concurrent Temporal Homogenization Method

    Shuo Yang1, Yongxing Shen1,*

    The International Conference on Computational & Experimental Engineering and Sciences, Vol.26, No.4, pp. 1-1, 2023, DOI:10.32604/icces.2023.09207

    Abstract Fatigue refers to repeated cyclic loading well below the ultimate failure stress of the structure. It accounts for most mechanical failures, and thus deserves serious consideration in engineering practice. Phase field approach is a powerful tool for fracture simulation, which tracks arbitrary and complicated crack paths without extra criterion. This approach has been widely applied to various cracking problems, such as shell fracture, beam fracture , etc. The phase field approach for fracture has been adapted for fatigue fracture in recent years. Due to the mesh requirement of the phase field approach and the large… More >
