This work is concerned with the Abaqus implementation of a suitable CAE methodology to get the most benefits of structural adhesive bonding. In this study, we are interested in cohesive debonding where the adhesive thickness and its non-linear behavior are of major importance. When subjected to loading, significant stress field gradients may develop around outer edges of the joint. Because such...

Abaqus/Standard simulation of Lamb waves in smart composite plates is investigated for detecting delamination type damage. Composite plates typical of aerospace structures are used and a PZT actuator is surface bonded to excite Lamb waves. Abaqus model of composite plate uses layered solid elements. Piezoelectric (PZT-5H) actuator is modeled using piezoelectric elements that have both displacem...

This thesis describes the process of detection, and if possible, also localization of the damage in non structural sheet-like materials. Simulation and analysis is carried out in ABAQUS with a FE model that has the same dynamic characteristics as the corresponding real material. Three types of damage forms are investigated: crack, hole and local weakness. Results presented in the report show th...

Although very accurate in representing the material anisotropy, finite element analysis based on direct use of a polycrystal model is CPU-intensive (Guan et al., 2006a). In the present study, this Taylor-type polycrystalline model was firstly used to predict the anisotropy coefficients of Yld96 yield function. Then this phenomenological anisotropic yield function was implemented into ABAQUS/Sta...

Commercial finite element software follow cautiously the numerical methods developed by scientific community. Even though phase-field method is not a default option in Abaqus, code proposes unique way to implement and test complex, extraneous models. In last five years, fracture models Abaqus have gained unbelievable popularity among scientists engineers alike. However, most implementations are...
