Either deformation in a plastic material, or fracture in a brittle one.
Oddly enough, a short bolt, tested to failure in a testing machine, will fail in the thread region due to the stress points inherent in the thread form.
Long bolts on the other hand, will fail in the shank.
This is usually explained by the idea that the bolt shank will break at its weakest point, and the longer the bolt, the more of the weak points, and the more of them, the weaker will be the weakest of them.
tension
It will break or fail. The type of failure will depend on how brittle/ductile it is. Brittle material will break cleanly, while ductile material will deform to varying degrees.
stress= force/C.S.A. so fracture stress = force at fracture / Cross.Sectional.Area.
depresion etc.
You should determine the tolerance for grain direction, including secondary grain direction if you have a single crystal material. You should evaluate it's effects on your structures harmonics and stress to see which gives you the most favorable results, then see how far you can deviate from that and still have acceptable life.
Normal stress acts perpendicular to the surface of a material, while shear stress acts parallel to the surface. Normal stress causes compression or tension, while shear stress causes sliding or deformation along the surface.
Normal stress acts perpendicular to the surface of a material, while shear stress acts parallel to the surface. Normal stress causes compression or tension, while shear stress causes deformation by sliding layers of material past each other.
to much stress on the product, there are many types of 'shear' but in its basic form the ammount of stress/preasure on the material causes it to fail
tension
The strain experienced by a material is directly related to the stress applied to it. When stress is applied to a material, it causes deformation or change in shape, which is known as strain. The relationship between stress and strain is described by the material's elastic properties, such as Young's Modulus. This relationship helps determine how a material will respond to external forces.
Elasticity is caused by the ability of a material to deform under stress and return to its original shape when the stress is removed. This is due to the arrangement of atoms or molecules in the material allowing for the absorption and release of energy. The strength of intermolecular forces in the material also plays a role in determining its elasticity.
Verticle stress causes monocline. Verticle stress causes monocline.
Bad Eating habits, excess stress and too much sun exposure are the most common.
Yes, stress can cause materials to stretch and elongate. This is due to the internal forces within the material rearranging to accommodate the external load applied.
Internal stress exceeds the strength of the material. The cause of the stress is that the "leading edge" of the object stops while the "trailing edge" is still moving.
This is a simple stress relieving process the welder can do to minimize warpage of material that was just welded.
To calculate strain from stress in a material, you can use the formula: Strain Stress / Young's Modulus. Stress is the force applied to the material, and Young's Modulus is a measure of the material's stiffness. By dividing the stress by the Young's Modulus, you can determine the amount of deformation or strain the material undergoes under the applied stress.
