Joining composites with metal parts leads to high stress concentrations because of the material property mismatch. Nature has found ingenious ways of joining dissimilar materials and making robust attachments, alleviating potential stress concentrations. A literature survey was conducted to identify the different joining methods used by nature. Biomimetic-inspired Single Lap joints (SLJs) were numerically investigated that offer a transitional zone of stiffness in the insertion site. It was found that the proposed biomimetic SLJs reduce the asymmetry of the stress distribution along the adhesive area.
