Effect of Anchor Threads on the Pullout Strength: A Biomechanical Study [PDF]
Journal of Orthopaedics, 2018 Pullout tests to determine the effect of anchor threads on the pullout strength was conducted by using universal testing machine, synthetic cancellous bone and thread-less metallic anchor. Anchors were inserted at 45°, 90° or 135° from the surface and they were pulled at 45° from the surface.

Pullout Strength Models for FRP Anchors in Uncracked Concrete
Journal of Composites for Construction, 2010 Mechanical anchorage can delay or even prevent premature debonding failure in externally bonded fiber-reinforced polymer (FRP) composite strengthening systems. A promising type of anchor made from FRP, which is known as a FRP spike anchor or FRP anchor among other names, is noncorrosive and can be applied to a wide range of structural elements and ...
