What is Strength of Material?

One of the crucial topics is the mechanics of strength, commonly known as the strength of materials or simple Som. It is almost the core of the mechanical engineering discipline. It primarily addresses how materials behave when they are subjected to an external load.

Some will describe the many forms of stresses, strains, breaks, and fractures that will occur in a material. A material's behavior aids in research, design, and the determination of whether it is appropriate for a given application.

A brief discussion about compressive strength

Compressive strength testing is a mechanical procedure that determines the maximum compressive load that a material can withstand before breaking. In order to compress the test component, which is commonly a cube, prism, or cylinder, between two platens, a compression-testing machine applies a constant load.

Concrete, rock, brick, cast iron, and other brittle materials can have great compressive strengths yet eventually fracture. The cube strength, which is used to quantify crushing strength, can be as high as 3 tonnes per square inch for cast iron, 10 tonnes per square inch for granite, and 25-60 tonnes per square inch for concrete.

Mild steel, for example, has a high compressive strength, although it might be challenging to evaluate the precise numbers. When a load is applied to a malleable metal, it first deforms plastically and then elastically up to a point. A test piece may even become fully flattened by increasing stresses without experiencing a clear fracture, so the compressive strength cannot be measured. The custom of stating tensile-strength figures in certain circumstances must be modified but kept safe, with compressive strength always being larger.

What is a compression testing machine?

A compression testing machine, often referred to as a "compression testing machine," is a vital mechanical apparatus used to evaluate the compressive strength and durability of materials. This device applies controlled pressure to a specimen, typically a concrete cylinder or cube, to measure its resistance to deformation or failure under compressive loads. It plays a pivotal role in construction, engineering, and material science, enabling accurate assessments of a material's load-bearing capacity. Whether in quality control or research applications, the compression testing machine serves as an indispensable tool to ensure the structural integrity and safety of various materials in diverse industries.

Types of compression testing machine

Compression testing equipment can be divided into two categories:

• Hydraulic compression test machine

Hydraulic compression testing equipment is the most common. Testing force is compressed by hydraulic fluid. Through the use of a pump and hydraulic fluid, the piston presses the specimen. This gadget can produce significant points during rigorous testing.

• Servo-electric compression testers

Testers for servo-electric compression are more recent and sophisticated. In comparison to hydraulic machinery, electric motors produce testing force more precisely and correctly. Servo-electric machines that are energy-efficient consume less energy than hydraulic ones do. These devices are used to test materials that need the application of precise force.

When deciding between hydraulic and servo-electric compression testing equipment, test needs, budget, and available space should be taken into account. It is essential to pick a machine that works with the intended application and test materials.

Conclusion

Strength is the ability of a substance to withstand a load without breaking or deforming plastically. The force and deformation that a substance produces define its power. The strength of a material is influenced by its mechanical properties, resistance to deformation, and elastic constants. HEICO Dynamics Pvt. Ltd. offers comprehensive support and machine expertise.
