Stress and strain may be described as follows in the case of a metal bar under tension. If a metal bar of cross-sectional area A is pulled by a force F at each end, the bar stretches from its original length L 0 to a new length L n. Simultaneously the cross section decreases.
For most metals, secondary creep is the dominant deformation mode at temperatures above half the melting point, TM , in degree Kelvin. The input we have for the analysis is a graph of strain Vs time. RadioHead - Creep. First the short-term elastic buckling of corrugated board panels was studied. The uniaxial creep test is simulated for epoxy.
Concrete is widely used in underground engineering and bears three-dimensional stress transmitted by overlying load. When a fire occurs, the thermal expansion of concrete structure under such stress state is different from that under stress-free state. For this purpose, a self-developed real-time high-temperature true triaxial test system was applied to investigate the thermal expansion behavior of concrete under three-dimensional stress state. The thermal expansion strain of concrete under the three-dimensional stress undergoes strain increasing and strain stabilizing stages. The average coefficient of thermal expansion of concrete under three-dimensional stress condition was then calculated, and its value reaches the minimum of 8.
Dynamic stress analysis of anisotropic gun barrel under coupled thermo-mechanical loads via finite element method. E-mail: yangyuzhao njust. This work focused on the stress response of anisotropic 30SiMn2MoVA steel gun barrel under coupled thermo-mechanical loads, namely, the contact pressure and friction of projectile, thermal load and pressure of propellant gas. The effect of temperature on the mechanical properties of gun barrel was considered. The first was the interaction model of projectile and barrel which was to calculate the stress of barrel engraved by copper jacket and steel jacket projectile. The results of barrel in the interaction model, as an initial condition, were imported to the second FEM which was applied with thermal load and pressure of propellant gas. The results show that the rifling at chamber throat has the largest stress and circumferential stress under coupled loads.
However, with the contemporary laboratory equipment, the experimental investigation of cell micromechanics has been a challenging task due to diminutive spatial and time scales involved. In this investigation, a three-dimensional 3-D coupled Smoothed Particle Hydrodynamics SPH and Coarse-Grained CG computational approach has been employed to model micromechanics of single plant cells going through drying or dehydration. This meshfree-based computational model has conclusively demonstrated that it can effectively simulate the behaviour of stress and strain in a plant cell being compressed at different levels of dryness: ranging from a fresh state to an extremely dried state. In addition, different biological and physical circumstances have been approximated through the proposed novel computational framework in the form of different turgor pressures, strain rates, mechanical properties and cell sizes. The proposed computational framework has potential not only to study the micromechanical characteristics of plant cellular structure during drying, but also other equivalent, biological structures and processes with relevant modifications.

Strength of materials , also called mechanics of materials , deals with the behavior of solid objects subject to stresses and strains. The theory began with the consideration of the behavior of one and two dimensional members of structures, whose states of stress can be approximated as two dimensional, and was then generalized to three dimensions to develop a more complete theory of the elastic and plastic behavior of materials. An important founding pioneer in mechanics of materials was Stephen Timoshenko. The study of strength of materials often refers to various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts.
Under these conditions the object returns to its original shape and size upon removal of the load. The deforming force may be applied to a solid by stretching, compressing, squeezing, bending, or twisting. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.
