"Concrete cone is one of the failure modes of anchors in concrete, loaded by a tensile force. The failure is governed by crack growth in concrete, which forms a typical cone shape having the anchor's axis as revolution axis. See more ACI 349-85 Under tension loading, the concrete cone failure surface has 45° inclination. A constant distribution of tensile stresses is then assumed.

Breakout failure is a concrete tensile failure that typically results in cracking at a 35 o angle from the base of the anchor to produce a cone. This type of failure can significantly limit the pull-out strength of the system.
