“…Moreover, it is assumed that the principal axes of material orthotropy of both the debonded face and the core are aligned with the co-ordinate axes of the specimen. The generalized Young's moduli associated with the orthotropy directions of each the material along the x-axis of the beam define the generalized stiffness values (13). The material properties of the sandwich specimen constituents are summarized in Table 1.…”

“…The use of the CEs for modelling progressive impact-induced delamination in laminated and sandwich panels have been performed, e.g. in [13,14]. A propagation of penny-shaped debonding in sandwich plates under general dynamic loading and penny-shaped delamination in laminates under fatigue have been simulated with CEs in [15] and [16], respectively.…”

Numerical simulations of dynamic fracture behaviour of a double cantilever sandwich beam subjected to uneven bending moments in plane conditions are carried out using the dynamic finite element analyses with the ABAQUSTM code. The strain energy release rate was evaluated by means of the finite element model developed within the two-dimensional (2-D) linear elastodynamic theory. This demonstrates the capability and the reliability of the finite element modelling as an extremely useful numerical tool for solving dynamic fracture mechanics problems. Also, the dynamic behaviour of fracture parameters and interface crack progression is discussed.

This article surveys existing cohesive zone models (CZM) and their use in numerical simulations for analysis impacts on composite structures and predicting the damage induced. These models are used for matrix cracks and delamination. The first part of article gives the required background on failure criteria for predicting the onset of delaminations, on fracture mechanics and the various types of CZM. The second part discusses applications of CZM to several types of impact problems with composite structures. Applications for these models to other problems are briefly mentioned at the end. CZM are now part of state of the art numerical simulations with progressive damage analysis.

“…Impact hazards also concern civil engineering and construction given that damage by hailstones to property accounts for one third of the total insured loss in Australia arising from natural hazards [Leigh, 2007]. Impact scenarios vary in scale from rockfalls [Hambleton et al, 2013] to the showering of storm debris onto building façades [Feng and Aymerich, 2013;Guo et al, 2013;Pyttel et al, 2011]. Large amount of impact related research has also been conducted in the field of bio-medical engineering (e.g., modeling of head injuries [Gong et al, 2008;Johnson and Young, 2005;Kerrigan et al, 2012;Zhang et al, 2001] and in research into damage to metal materials [Liu et al, 2005a;Liu et al, 2005b], composite materials [Khalili et al, 2011;Maio et al, 2013;Zhang et al, 2006], and to bone tissues [Delye et al, 2007;Yamashita and Gotoh, 2005].…”

Certain types of damage generated by the impact of a solid object are correlated with the amount of force that is localized around the area of contact between the impactor and the surface of the target. The stiffer the impactor, the higher the contact force when the amount of impulse delivered by the impact is held constant. Thus, realistic simulations of the contact force by finite element analysis (FEA) require representative, and detailed, information of the dynamic compressive properties of both the impactor and the target. In situations where relevant properties of the impactor material have not been documented, the estimation of contact force is filled with uncertainties. In addressing this challenge an innovative experimental-simulation calibration procedure involving the use of a custom made (inexpensive) tubular device is presented in this paper for measuring the dynamic compressive stiffness properties of impactor objects. Given the calibrated values the amount of contact force generated by the same impactor material in projected scenarios could be simulated with good accuracies for predicting damage.
