SIMPLE STRESS AND STRAIN 1.1 - Types of Load Load is an external force. Hydraulic force, steam pressure, tensile force, compressive force, shear force, spring force and different types of load. Again load may be classified as live load, dead load. Definition Strength of material is the study of the behaviour of structural and machine members unde The stress-strain diagram is of immense help in conveying information about mechanical properties and behaviour of the material. We shall restrict ourselves to behaviour of structural steel only. Our interest on structural steel stems out from the fact that, it is one of the most widely used metals, being used in buildings, bridges, towers, antennas and many more structures. Structural steel is also called low carbon steel or mild steel. A typical stress strain diagram for mild steel is as. شرح stress strain curve - YouTube. Watch later. Share. Copy link. Info. Shopping.

Simple Stress and Strain 2.1 Introduction When designing a structure or a machine, the engineer must estimate all the forces acting on the structure or the machine and its component parts. The. Basic Concepts (Contd) The limiting value of the stress upto which if the material is stressed and then released, strain disappears completely and the original length and the shape are regained is known as elastic limit. Hooke's law states that whenever a material is loaded within the elastic limit, the stress is proportional to th The stresses produced in the body due to change in its temperature are called temperature stresses and the corresponding strain produced are called temperature strains. If the temperature of the body is lowered, then the stress produced in the body will be tensile in nature whereas if the temperature of the body is raised, then the stress produced in the body will be compressive in nature w Simple Stress and Strain 3 1.5.

In continuum mechanics, stress is a physical quantity that expresses the internal forces that neighbouring particles of a continuous material exert on each other, while strain is the measure of the deformation of the material. For example, when a solid vertical bar is supporting an overhead weight, each particle in the bar pushes on the particles immediately below it

Stress and Strain are the two terms in Physics that describe the forces causing the deformation of the objects. Deformation is known as the change of the shape of an object by applications of force. Very small forces can also cause deformation. The object experiences it due to external forces; for example, the forces might be like squeezing. The stress-strain relationship of a material usually can be obtained from tensile or compression test on a specimen of the material. Figure 1.9 shows the stress-strain behavior which indicates how the material deforms on the application of load. The normal stress for the material is computed by dividing the load (P) by the original cross. When stress causes a material to change shape, it has undergone strain ordeformation. Deformed rocks are common in geologically active areas. A rock's response to stress depends on the rock type, the surrounding temperature, and pressure conditions the rock is under, the length of time the rock is under stress, and the type of stress Strain is a measurement of how an object reacts to stress. Strain is simply a measurement of what the percentage change in an object's shape is when a certain stress is applied to it. A good way to demonstrate strain is with a rubber band. Suppose we have a rubber band that is 100 inches long The three basic types of stresses are tensile, compressive and shear stresses. The stress developed in a body is said to be simple tension, simple compression and simple shear when the stress induced in the body is (a) single and (b) uniform

Basic Stress Equations Dr. D. B. Wallace Bending Moment in Curved Beam (Inside/Outside Stresses): Stresses for the inside and outside fibers of a curved beam in pure bending can be approximated from the straight beam equation as modified by an appropriate curvature factor as determined from the graph below [ i refers to the inside, and Clarification: According to Hooke's law, stress is directly proportional to strain and the ratio of stress to strain is denoted by Y or E and is called Young's Modulus oof elasticity. 5. Given the shear modulus(G) for aluminum as 2.4e +10 N/m 2 and the shear strain is given as 6e -5 Simple shear cannot be analysed, as while the stress axis remains constant with time, the strain axis rotates. This rotation gives the kinematics of the deformation also known as internal vorticity which is measured by its degree of non co-axiality or the degree it has deviated from the original parallel relationship between δ1// λ 3, δ 3. Young's modulus is a measure of the stiffness of an elastic material and is a quantity used to characterize materials. The slope of the stress-strain curve at any point is called the tangent modulus.The tangent modulus of the initial, linear portion of a stress-strain curve is called Young's modulus, also known as the Tensile modulus.It is defined as the ratio of the uniaxial stress over the. Stress can cause strain, if it is sufficient to overcome the strength of the object that is under stress. Strain is a change in shape or size resulting from applied forces (deformation). Rocks only strain when placed under stress. Any rock can be strained. Strain can be elastic, brittle, or ductile

Determine the intensities of normal, tangential and resultant stresses on a plane inclined at 30° anti-clockwise to the axis of the minor stress ries. The basic principles concerning the relationship between mechanical stress and strain of various materials were demon-strated by Robert Hooke (1635-1703) and proved to be essential for the improvement of bio-materials and the understanding of pathophysiological mechanisms in the vas-cular bed. Subsequently, the ground-break
