Figure 116. The liner penetrates the post when the post modeled with either elastic or wood material models. Diagrams.

Elastic material #1 post.

This figure shows a computer-generated illustration of a post embedded in a concrete brace using the single flap method. The post itself leans to the right a degree though no break or split has occurred. The post is simply bent over the side right hand side of the brace where the sleeve has begun to dig into the side of the post. The penetration point being circled highlights this event.

Wood material #143 post.

This figure shows a computer-generated illustration of a post embedded in a concrete brace using the single flap method. The top half of the post leans at a rough twenty-five degree angle. The post has split just below the surface in which it is embedded, with only a fraction of the post remaining to hinge the upper and lower halves together. With the top half of the post leaning to the right, the sleeve has begun to dig into the side of the structure. The penetration point being circled highlights this event.
