Fillet Weld Under Torsional Loading Calculator

Fillet welds are used for lap joints, corner joints, and T-shaped joints. A fillet weld is roughly triangular in cross-section, although its shape is not necessarily a right triangle or an isosceles triangle. The weld metal is deposited on the two members being assembled and penetrates and fuses with the base metal to form the joint formed corner.

This calculator is used to calculate the resulting stresses in welds.

Welding of approximately triangular cross-section joins two surfaces, approximately at right angles to each other, in a lap joint.

Stress is a measured average quantity of force per unit area. This is a measure of the strength of the total internal forces acting across the entire interior surface of a virtual body, as a reaction to externally applied forces and body forces.

In the stress state of shear stress, the stress is parallel or tangential to the surface of the material, rather than normal stress, when the stress is perpendicular to the surface.

The polar moment of inertia is a quantity used to predict the torsional resistance of an object in a constant circular section of the object (or segment object) without significant warping or out-of-plane deformation. It is used to calculate the angular displacement moment of an object. It is similar to moment of inertia, which is an object's resistance to bending and is required to calculate displacement.
