Case Study: University of California, Irvine perfects adhesive bond testing with MSC Nastran from Hexagon

MSC Nastran helps perfect new non-destructive testing method for adhesive bonded composites

Researchers at the University of California, Irvine were challenged to perfect a new non-destructive testing method for detecting weak adhesive bonds, known as kiss bonds, in composite materials. Conventional testing was unable to detect these flaws, which can compromise structural integrity and force manufacturers to add heavy, costly fasteners. To validate and refine their quantitative percussion testing technique, they turned to simulation software from vendor Hexagon.

Using Hexagon's MSC Nastran and Patran software, the UCI team built a high-fidelity finite element model to simulate the percussion testing. This virtual approach eliminated the need for expensive and error-prone physical test panels. The simulations successfully predicted force values that closely matched physical experiments, validating the method. Hexagon's solution enabled the researchers to efficiently perfect the testing technique, substantially reducing the time and cost required to bring it into widespread use.
