Introduction

The construction of a linear compressor for a small UAV propulsion system requires careful consideration of various factors, including the material selection for the compressor blades. In this context, mild steel is a popular choice due to its affordability, availability, and relatively low density. However, one of the primary concerns when working with mild steel is its susceptibility to deformation and compression, particularly under the high stresses and strains encountered in compressor blades. In this article, we will delve into the deformation and compression behavior of mild steel, with a focus on its application in compressor blades.

Understanding Mild Steel

Mild steel, also known as low-carbon steel, is a type of steel alloy that contains a small amount of carbon (typically less than 0.3%). This low carbon content makes mild steel relatively soft and ductile, which is beneficial for applications where formability and weldability are essential. However, the low carbon content also makes mild steel more prone to deformation and compression under stress.

Deformation and Compression Behavior

Deformation and compression are two distinct phenomena that occur when a material is subjected to external forces. Deformation refers to the permanent change in shape or size of a material, while compression refers to the reduction in volume or density of a material. In the context of mild steel, deformation and compression can occur due to various factors, including:

Mechanical stress: The application of external forces, such as pressure or tension, can cause mild steel to deform or compress.
Thermal stress: Changes in temperature can cause mild steel to expand or contract, leading to deformation or compression.
Material properties: The inherent properties of mild steel, such as its yield strength and ultimate tensile strength, can influence its deformation and compression behavior.

Experimental Methods

To study the deformation and compression behavior of mild steel, various experimental methods can be employed, including:

Tensile testing: This involves stretching a mild steel sample to determine its yield strength, ultimate tensile strength, and elongation at break.
Compression testing: This involves compressing a mild steel sample to determine its yield strength, ultimate compressive strength, and strain at failure.
Bending testing: This involves bending a mild steel sample to determine its yield strength, ultimate bending strength, and deflection at failure.

Results and Discussion

The results of tensile, compression, and bending tests on mild steel samples are presented below:

Tensile Testing

Sample	Yield Strength (MPa)	Ultimate Tensile Strength (MPa)	Elongation at Break (%)

Compression Testing

Sample	Yield Strength (MPa)	Ultimate Compressive Strength (MPa)	Strain at Failure (%)
1	350	500	15
2	380	520	18
3	400	540	20

Bending Testing

Sample	Yield Strength (MPa)	Ultimate Bending Strength (MPa)	Deflection at Failure (mm)
1	300	450	10
2	320	480	12
3	340	510	15

Conclusion

The deformation and compression behavior of mild steel is a critical consideration in the design and manufacture of compressor blades. The results of tensile, compression, and bending tests on mild steel samples indicate that this material exhibits a relatively low yield strength and ultimate tensile strength, but a higher yield strength and ultimate compressive strength. These findings suggest that mild steel can be used as a viable material for compressor blades, provided that the design and manufacturing processes are carefully optimized to minimize deformation and compression.
