Analysis of composite laminates with imperfect bonding conditions
2007
A multidomain boundary integral formulation for the analysis of composite laminates with imperfect interlaminar interfaces is presented. An imperfect interface refers to a zero-thickness interfacial layer across which displacement discontinuity may occur while interlaminar tractions must remain continuous. The displacement discontinuity is considered through a spring model in order to model the adhesive layer among two adjacent laminae. No auxiliary elements are needed to implement the imperfect interface since the spring coefficients, characterizing the different bonding interface conditions, are taken into account inside the assembled influence matrices. To assess the reliability and the …
Magneto-Electro-Elastic Bimorph Analysis by the Boundary Element Method
2008
The influence of the magnetic configuration on the behavior of magneto-electro-elastic bimorph beams is analyzed by using a boundary element approach. The problem is formulated by using the generalized displacements and generalized tractions. The boundary integral equation formulation is obtained by extending the reciprocity theorem to magneto-electro-elastic problems; it is numerically implemented by using the boundary element method multidomain technique to address problems involving nonhomogeneous configurations. Results under different magnetic configurations are compared highlighting the characteristic features of magnetopiezoelectric behavior particularly focusing on the link between …
