“…Experiments conducted by Brown [3] have shown that both strength and stiffness under tension, compression and shear were affected by strain rates ranging from 10 −3 /s to 10 2 /s. Thus, material models that take into account the strain rate effect can provide more accurate results when simulating impact loadings [4,5]. Zhikharev et al [6] studied ballistic limit in LS-DYNA® with a rate-sensitivity model for the prediction of delamination area and residual velocities applied to ballistic tests with a steel ball.…”

An effective and efficient methodology based on a strain-rate-dependent material model that can be applied to the simulations of ballistic impact on woven composites is presented in this paper. Firstly, a meso-heterogeneous model (fibre and matrix separately modelled) of R-glass-fibre woven composite was built and validated by tensile tests. Then, the model was used to obtain a strain-rate-dependent homogeneous material model with low computational cost and with a novel numerical environment to simulate high-velocity impact of the composite. Later, the proposed simulation framework was validated by conducting ballistic tests on the woven composite using full metal jacket (FMJ) projectiles. Exploiting strain-rate-dependent homogeneous material model, more accurate predictions of the composite delamination area and the residual velocity of projectiles were obtained compared to that without considering strain rate effects, especially for thick woven composites. The strain rate effect on targets with different thicknesses and the projectile deformation were also analysed.

This study focuses on the strain rate effect on the mechanical properties and damage evolution of basalt fiber reinforced composites subjected to low-velocity impact. A constitutive model is developed to accurately analyze the failure behavior of BFRP laminates. The strain-rate-dependent (SRD) model puts emphasis on a modified stress-strain relationship described by dynamic increase factor (DIF) to update mechanical properties timely during the impact loading and the damage evolution simulation is performed with the finite element code of ABAQUS software. The results shown in the LVI simulation confirmed the validity of the SRD model in comparison with the conclusions of experiments. Furthermore, detailed comparisons are discussed between the strain rate dependent (SRD) model and the strain rate independent (SRI) model under various simulations of different impact energy, thickness, and ply angles of laminates.

“…Although the overall behaviour of thermoplastic-based composites can be described in a purely phenomenological manner (Feld et al., 2018; Launay et al., 2011; Mandys et al., 2019; Vasiukov et al., 2015), such a modelling strategy generally leads to a large number of parameters that may be difficult to identify and their values are valid only for a unique microstructure configuration. This is a real limitation towards capturing accurately the local behaviour and deformation processes.…”

In this work, a multi-scale model established from the concept of periodic homogenization is utilized to predict the cyclic and time-dependent response of thermoplastic-based woven composites. The macroscopic behaviour of the composite is determined from finite element simulations of the representative unit cell of the periodic microstructure, where the local non-linear constitutive laws of the components are directly integrated, namely, the matrix and the yarns. The thermoplastic matrix is described by a phenomenological multi-mechanisms constitutive model accounting for viscoelasticity, viscoplasticity and ductile damage. For the yarns, a hybrid micromechanical–phenomenological constitutive model accounting for anisotropic damage and anelasticity induced by the presence of a diffuse micro-crack network is utilized. The capabilities of the overall multi-scale model are validated by comparing the numerical predictions with experimental data. Further illustrative examples are also provided, where the composite undergoes time-dependent deformations under uni-axial and non-proportional multi-axial loading paths. The multi-scale model is also employed to analyze the influence of the local deformation processes on the macroscopic response of the composite.
