PPT-MEASURING STRAIN When a force is applied to a structure, the components of the structure

Strain has units of inches per inch or millimeters per millimeter and hence is dimensionless In most structures the values of strain are usually very small for example a lowstrength steel will yield take a permanent deformation at a strain of only about 00014 As a result it is common to talk about strain in units of microstrain . Mohamed . Sherif. K, HSST Physics, GHSS . Athavanad. . Deforming Force & Restoring Force. A force which changes the shape and size of a body is called deforming force. When a deforming force is applied, the body may get deformed. Then the force developed inside the body, which try to bring the body back to its original shape and size is called restoring force..

Whenever a force is applied to a body, it will undergo deformation (change the body's shape and size). The deformation can be highly visible, but is often unnoticeable. Generally, the deformation of a body will not be uniform throughout its volume . Engr. . Hinesh. Kumar (Lecturer)O. Outline. Differentiate between the terms “Sensor”, “Transducer” & “Actuator”.

It is the expression of force per unit area to structural members that are subjected to external forces and/or induced forces. Stress is the lead to accurately describe and predict the elastic deformation of a body. . MSc . Sadiq Almayali. Mechanical properties of dental material. Introduction. To select and use a dental material one must understand its properties. Knowledge of the properties of the material predicts its behavior, functioning in the mouth and longevity. Accordingly, one can optimize design and techniques in order to get the best out of a particular material.. where δ is the deformation and L is the original length, thus ε is dimensionless. . Stress-Strain Diagram . Suppose that a metal specimen be placed in tension-compression testing machine. As the axial load is gradually increased in increments, the total elongation over the gage length is measured at each increment of the load and this is continued until failure of the specimen takes place. Knowing the original cross-sectional area and length of the specimen, the normal stress σ and the strain ε can be obtained. The graph of these quantities with the stress σ along the y-axis and the strain ε along the x-axis is called the stress-strain diagram. The stress-strain diagram differs in form for various materials. The diagram shown below is that for a medium carbon structural steel. . Learning Lunch. 2/15/19. Biomechanics?.

Introduction to Stress and Strain (Lesson). Mechanical Engineers characterize materials using forces, stress, and strain. They analyze the behavior of materials in order to define safety constraints. In simple terms, they need to determine how much stress can be applied before the material breaks or becomes permanently deformed. Biomedical engineers test materials to strengthen or replace tissues or broken bones..
