Efficient non-iterative modelling of pressure-dependent plasticity using paraboloidal yield criterion

A full understanding of the non-linear mechanical response polymer is essential for fibre-reinforced composite design because an explicit definition constitutive material models constituents (fibres, matrix, and interface) are prerequisite in micromechanical simulations. Unlike ductile metals, behaviour matrix characterised by plasticity theories influenced a combination distortional spherical energy dissipation. In this respect, elastoplastic thermodynamic continuum model derivation proposed using paraboloidal yield criterion under isothermal conditions. non-iterative scheme developed numerical computation plastic strain increment multiplier. Both associated non-associated flow rules investigated following classical loading–unloading It thereby, evades conventional computationally demanding iterative process replacing it with exact determination increment. This novel approach highly improves computational efficiency algorithmically. The real-sized comparison between simulated experimental results shows reliability unprecedented accuracy mathematical model.
