Sheet metal is
Sheet metal is available in flat pieces or coiled strips. The coils are formed by running a continuous sheet of metal through a
In most of the world, sheet metal thickness is consistently specified in millimeters. In the US, the thickness of sheet metal is commonly specified by a traditional, non-linear measure known as its
There are many different metals that can be made into sheet metal, such as
Sheet metal is used in automobile and truck (lorry) bodies, airplane fuselages and wings, medical tables, roofs for buildings (architecture) and many other applications. Sheet metal of iron and other materials with high magnetic
Grade 304 is the most common of the three grades. It offers good corrosion resistance while maintaining
Grade 316 possesses more corrosion resistance and strength at elevated temperatures than 304. It is commonly used for
Grade 430 is popular grade, low cost alternative to series 300's grades. This is used when high corrosion resistance is not a primary criterion. Common grade for appliance products, often with a brushed finish.
Grade 1100-H14 is commercially pure aluminium, highly chemical and weather resistant. It is ductile enough for
Grade 3003-H14 is stronger than 1100, while maintaining the same formability and low cost. It is corrosion resistant and weldable. It is often used in
Grade 5052-H32 is much stronger than 3003 while still maintaining good formability. It maintains high corrosion resistance and weldability. Common applications include electronic chassis, tanks, and
In sheet hydroforming, variation in incoming sheet coil properties is a common problem for forming process, especially with materials for automotive applications. Even though incoming sheet coil may meet tensile test specifications, high rejection rate is often observed in production due to inconsistent material behavior. Thus there is a strong need for a discriminating method for testing incoming sheet material formability.The hydraulic sheet bulge test emulates biaxial deformation conditions commonly seen in production operations.
For Forming Limit curves (FLCs)of materials Aluminium, Mild steel and Brass.Theoretical analysis is carried out by deriving governing equations for determining of Equivalentstress and Equivalent strain based on the bulging to be spherical andTresca’s yield criterion with the associated flow rule. For experimentation Circular Grid Analysis is used.
