Continuum mechanics cTopic SolidmechanicsSolidmechanics is the branch of mechanics , physics , and mathematics that concerns the behavior of solid matter under external actions e.g., external force s, temperature changes, applied displacements, etc. . It is part of a broader study known as continuum mechanics . One of the most common practical applications of solidmechanics is the Euler Bernoulli beam equation . Solidmechanics extensively uses tensor s to describe stresses, strains, and the relationship between them. Relationship to continuum mechanics As shown in the following table, solidmechanics inhabits a central place within continuum mechanics. The field of rheology presents an overlap between solid and fluid mechanics fluid mechanics. Continuum mechanics context Response models A material has a rest shape and its shape departs away from the rest shape due to stress. The amount of departure from rest shape is called Deformation mechanics deformation , the proportion of deformation to original size is called strain. If the applied stress is sufficiently low or the imposed strain is small enough , almost all solid materials behave in such a way that the strain is directly proportional to the stress the coefficient of the proportion is called the modulus of elasticity or Young ... for analysts in solidmechanics to use linear material models, due to ease of computation.

Merge Mechanics of structures date September 2010 Structural mechanics is the computation of deformation engineering deformation s, deflection s, and internal force s or stress physics stress es stress equivalents within structures, either for design or for performance evaluation of existing structures. It is one subset of structural analysis. Structural mechanics analysis needs input data such as structural load s, the List of structural elements structure s geometric representation and support conditions, and the materials properties. Output quantities may include support reactions, Stress physics stresses and Displacement vector displacements . Advanced structural mechanics may include the effects of stability and non linear behaviors.

Unreferenced date July 2008 Mechanical failure modes In mechanics , an impact is a high force or Shock mechanics shock applied over a short time period when two or more bodies collide. Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer time period of time. The effect depends critically on the relative velocity of the bodies to one another. At normal speeds, during a perfectly inelastic collision , an object struck by a projectile will deform, and this deformation will absorb most, or even all, of the force of the collision. Viewed from the conservation of energy perspective, the kinetic energy of the projectile is changed into heat and sound energy, as a result of the deformations and vibrations induced in the struck object. However, these deformations and vibrations can not occur instantaneously. A high velocity collision an impact does not provide sufficient time for these deformations and vibrations to occur. Thus, the struck material behaves as if it were more brittle than it is, and the majority of the applied force goes into fracturing the material. Or, another way to look at it is that materials actually are more brittle on short time scales than on long time scales this is related to time temperature superposition . Different materials can behave in quite different ways in impact when compared with static loading conditions. Ductile materials like steel tend to become more brittle at high loading rates, and spalling may occur on the reverse side to the impact if penetration doesn t occur. The way in which the kinetic energy is distributed through the section is also important in determining its response.

Rock mechanics is the theoretical and applied science of the mechanical behaviour of rock and rock masses it is that branch of mechanics concerned with the response of rock and rock masses to the force fields of their physical environment. Rock mechanics itself forms part of the broader subject of geomechanics which is concerned with the mechanical responses of all geological materials, including soils. Rock mechanics, as applied in mining , petroleum, and civil engineering practice, is concerned with the application of the principles of engineering mechanics to the design of the rock structures generated by mining, drilling, reservoir production, or civil construction activity, e.g. tunnels , mining shafts, underground excavations, open pit mines, oil well oil and gas wells , road cuts, waste repositories, and other structures built in or of rock. It also includes the design of reinforcement systems such as rock bolt ing patterns.
