Have you ever wondered about how sheet metal is formed to create everything from car parts to household appliances? Sheet metal forming is an essential manufacturing process that’s used in a wide range of industries. In this article, we’ll dive into the fundamentals, techniques, and best practices of sheet metal forming, so you can level…
Have you ever wondered how metal products are made? From cars to household appliances, there are many items that are made from sheet metal. The process that is used to create these products is called sheet metal stamping or forming. Basic Concepts of Sheet Metal Forming So what is sheet metal stamping? Sheet metal Forming…
What is fatigue stress in engineering? So, what exactly is fatigue stress? Basically, it’s when a component or structure starts to weaken and break down over time due to cyclical stress or loading. Even if the stresses put on the component are within acceptable limits, fatigue failure can still occur due to the frequency of…
Crashworthiness refers to a structure’s ability to reduce the number of fatal and serious injuries that occur in an impact/ accident. Most commonly assessed in aviation and automotive safety. Various criteria determine crash safety, depending on impact type and vehicle. Evaluation can be performed through finite element analysis which is a form of computer-aided engineering…
Have you ever wondered why are cars so heavy? it seems like each year that goes by cars seem to get bigger and heavier! The average weight of a recently purchased vehicle in the United States reached a 4,329 pounds in 2022. This figure exceeds the 1980 average by over 1,000 pounds and reflects an…
The automotive body structure is one the main and most important components of a modern automobile. This system serves as the cohesive link for all other subsystems, accommodating the drivetrain and primarily providing support and protection for passengers and cargo. A robust body structure is imperative to withstand loads, and pressure, and effectively unify all…
What is meant by dual-phase steel? Developed in the 1970s, dual-phase steel (DP) is a high-strength steel that provides theadvantages of high-strength steel without losing good overall elongation. As a result of itsmicrostructure consisting of both ferritic–martensitic microstructure. DP steel has good fatigue resistance making it ideal for automotive-related sheet-forming operations. Mechanical properties of common…
The car top or automobile roof of an automobile is the part of the vehicle situated above the passenger compartment, shielding the vehicle occupants from external elements such as sun, wind, and rain. When did cars start having roofs? Initially, cars lacked roofs altogether. Subsequently, these early vehicles being influenced by the era of horse-drawn…
Torsional and bending rigidity is a critical parameter for any automobile, especially vehicles with a unibody construction. However, bending rigidity isn’t as critical as torsional rigidity in the design of a vehicle. Unibody torsional rigidity is a measure of the force required to induce a one-degree “twist” in a car’s body structure. Naturally, a higher…
