# Verification Examples

Motto:

,,There is singularity between linear and nonlinear world.”

*(Dr. Imre Bojtár)*

Verification Examples is a collection of calculation examples that compare FEM-Design analysis with hand calculations.

We are continuously developing this verification book therefore some discrepancy in the numbering of the chapters or some missing examples can occur. The Verification Manual is available as pdf book.
