AbstractThis report discusses finite element modeling of progressive damage in the adhesive bond layers of actuated plates and investigates the reduction in actuation capacity caused by the damaged bond layers. The primary challenge posed by this class of problems stems from the vast range of geometric scales that are represented, with the thickness of the adhesive layer representing the smallest scale, the overall thickness of the actuated plate representing the intermediate scale and the in-plane dimensions of the plate representing the largest scale. In multiscale problems, the overall efficiency of the numerical methodology is of paramo unt importance, thus model development is guided by the need to obtain a sufficiently accurate solution at an acceptable computational expense. In this study, this goal is achieved by through the use of a hierarchical, displacement-based, 2-D finite eleme nt model that includes the first-order shear deformation model (FSD), type-I layerwise models (LW1) and type-II layerwise models (LW2) as special cases. Both the LW1 layerwise model and the more familiar FSD model use a reduced constitutive matrix that is based on the assumption of zero transverse normal stress; however, the LW1 model includes discrete layer transverse shear effects via in-plane displacement components that are C 0 continuous with respect to the thickness coordinate. The LW2 layerwise model utilizes a full 3-D constitutive matrix and includes both discrete layer transverse shear effects and discrete layer transverse normal effects by expanding all three displacement components as C 0 continuous functions of the thickness coordinate. The hierarchical finite element model incorporates a 3-D continuum damage mechanics model that predicts local orthotropic damage evolution and local stiffness reduction at the geometric scale represented by the individual material ply or, in the case of layerwise models, by the individual numerical layer. The results clearly demonstrate that the resulting model can efficiently simulate progressive damage in the adhesive layers. For rectangular actuator patches, the adhesive damage is highest near the corners of the actuator and is driven primarily by local concentrations...

A Strain Rate Dependent Damage Model for Evaluating the Dynamic Response of CFRTP Laminates with Different Stacking Sequence

“…𝑑 represents the damage in direction 3, which can be quantified as the out of plane damage distribution density (Figure 2c). The value of 𝑑 is between 0 and 1. 𝑑 = 0 represents the material is no damage in direction 𝑖; 𝑑 = 1 represents the material fails in direction 𝑖 [30]. An energy-based criterion is used to describe the nonlinear damage evolution as [31]:…”

Repair of a delaminated plate under static loading with piezoelectric patches

“…The effects of plate delamination geometries on critical loads were discussed. Robbins studied progressive damage in a piezoelectric bonded plate using the FEM (Robbins and Chopra 2007). The reduction in the actuation capacity caused by damaged bond layers was investigated at the same time.…”
