Corner Singularity App – SingSol

SingSol is a web application developed to facilitate the analysis of stress and displacement singularities in multimaterial corners, under homogeneous and frictional boundary conditions. It is specifically designed for use with composite materials, structural adhesives, and geometries with material and/or geometric discontinuities.

🔍 What does it allow you to do?

• Calculate singularity exponents and associated fields (stress and displacement) in 2.5D configurations.
• Define open or closed corners with multiple isotropic, orthotropic, or transversely isotropic materials.
• Select boundary conditions (free, embedded, symmetry, etc.) and interfaces (perfectly bonded or frictionless contact).
• Obtain highly accurate results using semi-analytical methods based on the Stroh formalism.
• View the results and receive a full PDF report by email.
