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.
What else can I help you with?
A stress that causes a material to fracture where the fracture opens or spreads apart is?
tension
What will happen to a material if the stress exceeds the ultimate strength?
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.
How do Calculate engineering fracture stress?
stress= force/C.S.A. so fracture stress = force at fracture / Cross.Sectional.Area.
What is the tolerance for grain direction?
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.
What does stress cause?
depresion etc.
What is the difference between normal stress and shear stress in the context of material deformation?
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.
What is the difference between normal and shear stress in materials?
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.
What exactly causes shear?
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
A stress that causes a material to fracture where the fracture opens or spreads apart is?
tension
How does the strain experienced by a material relate to the stress applied to it?
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.
What causes elasticity?
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.
What refers to an excess of changes that stay in place on a material?
An excess of changes that remain in place on a material is often referred to as "residual stress." This phenomenon occurs when a material undergoes deformation or alterations during processes like manufacturing or cooling, yet does not fully return to its original shape. As a result, internal stresses can develop, which may affect the material's performance and longevity. Residual stress is crucial to consider in fields like engineering and materials science.
What causes a stress?
Verticle stress causes monocline. Verticle stress causes monocline.
What causes a bloody nose and blurred vision?
Bad Eating habits, excess stress and too much sun exposure are the most common.
Is the stress that causes stretching and elongation.?
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.
What causes an object to break on impact?
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.
Welding post heating?
This is a simple stress relieving process the welder can do to minimize warpage of material that was just welded.
