Q&A: What is stress? What is stress concentration?
Stress refers to the force acting per unit area; it is conceptually similar to pressure. Stress emphasizes the forces acting within a material. Stress concentration occurs mainly due to the heterogeneity within the material, causing stress levels in certain areas to be much higher than the average stress level

Stress refers to the force acting per unit area; it is conceptually the same as pressure, with stress emphasizing the forces acting within a material. Stress concentration is mainly caused by the heterogeneity within a material, resulting in stress levels in certain areas being much higher than the average stress level.
Stress is the effect produced by a load. Stress concentration is a phenomenon in which local stress increases due to a sudden change in the cross-sectional dimensions of a component
Stress refers to the force acting per unit area; there are stresses in different directions, such as normal stress, shear stress, and principal stresses. . Stress concentration refers to the phenomenon in which the maximum stress value in a local area of a structure or component is higher than the average stress value.
Stress: When an object deforms due to external factors (such as forces, humidity, changes in temperature fields, etc.), internal forces arise between various parts of the object in order to resist these external influences and attempt to restore the object to its original shape after deformation. Stress concentration: A type of problem in elasticity mechanics referring to the local increase in stress within a material, which generally occurs at places where the shape of the material changes abruptly, such as notches, holes, grooves, and areas under rigid constraints.
The force per unit area acting on a constant-cross-section object is called stress
Changes in the cross-sectional dimensions of mechanical components, as well as grooves and small holes, lead to stress concentration.
Stress concentration refers to the phenomenon in which a stressed component experiences a significant increase in stress in a local area due to sudden changes in its geometric shape or dimensions.
When a material deforms, equal in magnitude but opposite in direction reaction forces are generated within it to resist the external force; this reaction force per unit area is defined as stress. Stress concentration refers to the phenomenon in which a stressed component experiences a significant increase in stress in a local area due to external factors or changes in its geometric shape and dimensions.
