“…Having taken the flexibility, polarizability, and nuclear quantum effects of water into consideration, the ab initio optimized molecular dynamics (MD) force field, the Condensed-phase Optimized Molecular Potentials for Atomistic Simulation Studies (COMPASS) 27, [141] is an elegant approach. This package derives the phonon (power) spectra in terms of Fourier transformation of molecular velocity autocorrelation function, [145]. A 360-molecule supercell of proton-disordered ice Ih was simulated (in which the proton was sufficiently optimised to avoid a net dipole moment or to minimise a net quadruple moment [146]).…”

“…An advantage of the phenomenological DIF formulation in Eq. (12) and (13) is that it can accommodate both a positive and negative influence of displacement jump rate on either cohesive strength or fracture energy while the existing rate-dependent CZMs developed with damage-delay [7,25,26] or viscosity formulation [27][28][29][30][31][32] can only capture a positive influence. This versatility provides more possibilities in describing different failure mechanisms in different composite material system and loading conditions.…”

The mode-I interlaminar fracture toughness of composite laminates under different loading rates can be measured by the double cantilever beam (DCB) test. It is observed from the DCB test of a unidirectional PEEK/carbon composite laminate that as the loading rate increases from quasi-static to dynamic range: (1) delamination crack growth exhibits a transition from stable to unstable ("stick/slip") and back to a stable type; (2) the interlaminar fracture toughness is not constant as the loading rate increases. In this paper, two numerical approaches are used to reproduce the experimental observations: a cohesive zone model (CZM) and the interfacial thick level set (ITLS) model. CZM simulations with rate-independent and rate-dependent cohesive laws are carried out. A new version of the ITLS is introduced with a phenomenological relation between crack speed and energy release rate. The simulation results of the CZM and the ITLS model are compared with the real DCB test data to evaluate the capability of these two types of models. It is found that the used CZM can reproduce rate-dependence of the fracture energy, but not the stick/slip behavior. The ITLS can capture the stick/slip behavior, but needs different parameter sets for different loading rates.

Mechanical Identification of Materials and Structures with Optical Methods and Metaheuristic Optimization

This study presents a hybrid framework for mechanical identification of materials and structures. The inverse problem is solved by combining experimental measurements performed by optical methods and non-linear optimization using metaheuristic algorithms. In particular, we develop three advanced formulations of Simulated Annealing (SA), Harmony Search (HS) and Big Bang-Big Crunch (BBBC) including enhanced approximate line search and computationally cheap gradient evaluation strategies. The rationale behind the new algorithms—denoted as Hybrid Fast Simulated Annealing (HFSA), Hybrid Fast Harmony Search (HFHS) and Hybrid Fast Big Bang-Big Crunch (HFBBBC)—is to generate high quality trial designs lying on a properly selected set of descent directions. Besides hybridizing SA/HS/BBBC metaheuristic search engines with gradient information and approximate line search, HS and BBBC are also hybridized with an enhanced 1-D probabilistic search derived from SA. The results obtained in three inverse problems regarding composite and transversely isotropic hyperelastic materials/structures with up to 17 unknown properties clearly demonstrate the validity of the proposed approach, which allows to significantly reduce the number of structural analyses with respect to previous SA/HS/BBBC formulations and improves robustness of metaheuristic search engines.
