The Composites Affordability Initiative (CAI) unanimously selected ESRD’s composites functionality to “replace as well as radically improve existing industry software currently used for bonded joints.” In time, the improvements extended to fastened laminated composite and metallic-laminated joints, reinforced composite structures, multi-scale analysis and more.
Instead of plate or shell modeling, we focus on the important details, such as interlaminar failure modes and thru-thickness ply stresses.
Our implementation is unique in the FEA industry for focusing on the detailed analysis needs of composite designers and engineers, including 3D ply-by-ply modeling and failure analysis.

The finite element method is used by engineers daily in the design/assessment of components and structures. The number of engineers using such tools is increasing and will increase further with the so-called democratisation of simulation. However, whilst the method might appear easy to use, with highly effective graphical user interfaces, the fundamental fact is that it is approximate and can produce significant errors in the hands of the inexperienced engineer. These errors, if undetected, can compromise a design to such an extent that it becomes unfit for purpose or, even, unsafe. The way to avoid such finite element malpractice is through the application of sound simulation governance.
