Romar Adds to Capability with In-House Tensile Testing
With our broad expertise across areas including advanced manufacturing, elastomers, silicone and medical device manufacturing, Romar Engineering is uniquely positioned to provide tailored and robust manufacturing solutions.
We’ve recently added to our capability with in-house tensile testing. This process is essential to measure material performance, verify processing conditions and ensure projects effectively meet Australian Government ASTM and ISO standards. Tensile testing is crucial for the development of high-performance materials in sectors such as aerospace, medical, mining and defence.
Most Australian manufacturers rely on external tensile testing. With in-house testing capability, we’re equipped to streamline and enhance our material selection and processing development, design for manufacture and commercial manufacture processes – thanks both to the technology, and our skilled engineers who can make meaningful sense of the data, to formulate enhanced customer solutions.
What is tensile testing?
Tensile testing is a performance test used to measure mechanical properties such as tensile strength, yield strength and ductility.
With tensile testing, we analyse how a material performs under load and the amount of force required to reach point of fracture.
By analysing stress and strain data, we can measure material behaviour in various processing conditions. We employ tensile testing to gauge properties including:
- Tensile strength – also referred to as Ultimate Tensile Strength (UTS); the maximum stress a material can withstand without fracture; measured in various environments including extreme heat and cold. Stress is the amount of force divided by the original cross-sectional area of the sample under test and has units in pounds per square inch or megapascals.
- Yield strength – the point at which plastic deformation occurs under stress; also defined as the greatest stress achievable without loss of proportion of stress and strain.
- Ductility – the ability of a material to be drawn or plastically deformed without fracture; an indication of material softness or malleability.
- Resilience – a material’s ability to absorb and store energy during a tensile loading application.
- Modulus of elasticity – the measurement of a material’s stiffness.
- Poisson’s Ratio – a material’s lateral deformation compared to the axial or longitudinal deformation.
Why use tensile testing?
The Romar Engineering team conducts tests in accordance with global ASTM and ISO standards, with testing and measuring procedures dependent on the material under investigation and its intended application.
Tensile testing is crucial to help avoid costly and potentially dangerous equipment or part failure.
In the event of component failure, tensile testing is often used in combination with metallography to investigate failure conditions.
It also provides us with valuable data on material properties, which we use in the development of our bespoke metal additive process parameters and custom elastomer formulations.
Tensile testing has a variety of uses, including:
- Validating material processing parameters
- Failure analysis
- Establishing statistically based mechanical properties per MMPDS guidelines
- Evaluating novel additive manufacturing geometries
- Demonstrating proof of concept for new projects
- Determining if a material meets precise industry standards
- Establishing relevant statistical basis for metal additive processes
- Observing quality variations for Romar production parts
Benefits of in-house tensile testing
At Romar, we use tensile testing to identify potential material flaws and weaknesses prior to manufacture, to optimise structural and functional integrity, and to ensure the material meets the original project aim.
Leading Australian manufacturing
Our new tensile testing capability adds to our world-class facilities and extensive laboratory testing processes, which also include rheological testing, durometer hardness testing, Vickers hardness testing and surface finish testing.
