The study of how materials react to forces, including stress, strain, and deformation.
Stress analysis: The study of the distribution of internal forces within a material due to external loads.
Strain analysis: The study of the deformation of a material under external loads.
Material properties: The characteristics of materials that affect their ability to withstand external loads, such as elasticity, yield strength, and ductility.
Stresses due to bending: The forces that act on a beam when it is loaded in a way that causes it to bend.
Axial stresses: The forces that act on a material when it is subject to an axial load, or a force that is applied in the direction of its length.
Torsional stresses: The forces that act on a material when it is twisted around its length.
Shear stresses: The forces that act on a material when it is subject to a shear load, or a force that is applied parallel to its surface.
Combined stresses: When a material is subject to multiple types of stresses at the same time.
Deflection of beams: The amount of bending that a beam undergoes when it is subject to a load.
Buckling of columns: The instability that occurs when a column is loaded in such a way that it causes it to buckle or fail.
Failure criteria: The conditions under which a material will fail, such as when it is subject to excessive stress or strain.
Plastic deformation: The permanent deformation that occurs in a material when it is subject to stresses beyond its elastic limit.
Statics: This is the study of forces that are in equilibrium or balanced, such that there is no motion.
Dynamics: This is the study of forces that are not in equilibrium, or that cause motion in mechanical systems.
Strength of Materials: This is the study of how materials respond to external forces.
Fracture Mechanics: This is the study of how materials break or fail under stress, and how to prevent such failures.
Elasticity: This is the study of the deformation of materials under external forces and how these deformations affect the mechanical properties of the material.
Plasticity: This is the study of how materials deform and flow under external forces beyond their elastic limit.
Fatigue: This is the study of the weakening of materials over time due to cyclical loading.
Buckling: This is the study of the buckling failure modes of materials, particularly thin-walled structures.
Creep: This is the study of how materials deform over time under constant loads or elevated temperatures.
Residual Stress: This is the internal stress of a material that remains after the external forces have been removed, which can affect the strength and durability of the material.
Composite Materials: This is the study of how composite materials are designed and analyzed for structural applications.
Failure Analysis: This is the study of how materials and structures fail under various loading conditions, and how to improve their safety and reliability.
