I have a 1/2" thk plate with a bolt/nut going through a hole, assuming there's a weight on the bolt what would be the difference between the Tear Out Stress and the Bearing Stress?? |

Tear out is when the pin literally rips through the material under load. It can also describe the pin tearing a coupon of material from the plate if the hole is too close to the edge of the plate. Bearing is a local phenomenon and deals with local deformation of the pin and/or hole at their contact surface. |

no. Bearing stress is a compressive stress. Tearout is a shear stress. These two stresses act on different geometries as well. The bearing stress acts on the outside of the bolt and the inside walls of the hole. Shear stress acts on the cross section of the bolt and the tangent cross section of the hole perpendicular to the axis of the hole or bolt. |
