Unraveling the Mystery of Engineering Strain: A Comprehensive Definition for Novice Engineers

Engineering strain, otherwise known as tensile strain, is a term commonly used in the field of engineering to describe the deformation of a material caused by an applied force or load. As a novice engineer, understanding the concept of engineering strain can be challenging. However, with the right resources and guidance, anyone can comprehend this fundamental aspect of engineering. In this blog post, we will provide a comprehensive definition of engineering strain, discuss its types, applications, and provide a comparison between engineering strain and other related concepts.

Understanding Engineering Strain

Engineering strain is defined as the ratio of the change in length (deformation) of a material, to its original length, caused by an applied external force.

where:

• ε = engineering strain
• ΔL = change in length
• L = original length

For example, if a material with an original length of 10 cm elongates to 12 cm when subjected to an external force, the engineering strain would be calculated as:

Therefore, the engineering strain in this instance would be 0.2 or 20%.

Types of Engineering Strain

Linear Strain

Linear strain is the engineering strain experienced by a material when subjected to a tensile or compressive force, resulting in a change in length along the axis of the force.

Shear Strain

Shear strain is the engineering strain experienced by a material when subjected to a shear force resulting in deformation along an axis perpendicular to the applied force.

Applications of Engineering Strain

Engineering strain plays a crucial role in different fields, ranging from civil engineering to aerospace engineering. In structural engineering, the concept of engineering strain is used to design and analyze buildings, bridges, and other structures. In the aerospace industry, it is used to analyze and design aircraft and spacecraft components, including wings, fuselage, and engines.

Comparison between Engineering Strain and other Related Concepts

Engineering strain is often confused with other related concepts such as true strain, stress, and Young's modulus. However, each concept has its unique characteristics that distinguish it from the others.

People Also Ask:

1. What is engineering strain?

Engineering strain refers to the deformation or change in shape that occurs in a material under external forces or loads.

2. How is engineering strain calculated?

Engineering strain is calculated by dividing the change in length of a material by its original length, represented by the symbol ε.

3. What is the difference between engineering strain and true strain?
