What exactly is an ampere? What is physical metallurgy? What does the resistivity of a wire depend on? What is welding metallurgy? What is stress and strain in mechanical engineering? What is industrial metallurgy? What supplies potential difference to a circuit?
response to the applied stress is permanent, meaning that the material does not recover when the stress is removed. The relationship between stress and strain in this region is nonlinear. It depends on the properties of the material, such as its yield strength, ultimate strength, and ductility....
Strain is the deformation of materials under stress, focusing on the internal changes, while tension refers to the force stretching a material, emphasizing external stress.
Figure6: Ultimate Strength and Yield strength can be determined from static stress-strain tests。 For example, the Ultimate Strength stress is the value that causes a failure for one cycle. The Yield Strength stress level divides the plastic and elastic region. 例如,极限强度应力是单个周期就引起失...
When a ductile material, such as copper or aluminum, is put under stress, initially, the resulting strain is proportional to the magnitude of the forces. This is depicted by the straight-line OA. The straight-line implies that stress and strain share a linear or direct relationship throughout...
(STRESS) ij = C ijkl (STRAIN) kl That's what tensors are. The "stress tensor" then is (in 3-space) the 3 x 3 symmetric matrix which describes the state of stress. From this, all other stress quantities can be derived (Von Mises, Principal stresses and directions, etc)....

Strain also has a direction and the plus or minus sign is attached to express the direction of expansion or contraction. Pulling (expansion): plus, contraction: minus Price Relationship Between Stress and Strain The relationship between stress and strain has been obtained experimentally. ...
Hooke's law states that strain is directly proportional to stress. The modulus of elasticity is used as a constant of proportionality in Hooke's law. For the stress-strain curve, the validity of Hooke's law is determined by the elastic limit. ...
In the postprocessor I get strain, non-linear strain, stress and non-linear stress. The values for strain and non-linear strain are identical, as are the values for stress and non-linear stress. I do not understand that. What is ...
