When the wood buckles and shears on the inside of the bend. If using a compression strap, often tiny little crinkles are visible on the inside of the bend. These can be sanded or machined off to leave a smooth surface. This is not a failure, as the overall structural integrity of the wood is intact. A failure is when part of the wood has actually sheared off the rest, often resulting in the bend not having the desired shape. The solution to compression failure is normally using different wood, the addition of clamps across the width of the wood prior to bending, reducing the tightness of the strap during the bend, or making the bend more gentle in your design.
