Today, we’re wrapping up our exploration of mechanical properties by diving into two key topics: impact strength for plastics and tear resistance for rubber. In this post, we’ll look at how these properties help materials survive sudden forces, such as a plastic’s ability to withstand shock impacts or rubber’s durability in preventing small tears from turning into larger problems. We’ll discuss the tests used to measure these properties, explain why tensile strength alone doesn’t tell the full story, and highlight the materials that excel in handling the tough demands of real-world conditions.
Welcome back to our series, “From Data Sheets to the Real World: A Practical Guide to Material Properties.” In this post, we’re diving into flexural properties, which are often overshadowed by tensile strength but are just as critical in real-world applications. We’ll explore flexural strength and modulus, explaining why they’re key for materials facing bending forces, such as in aerospace and automotive components. You’ll also discover why tensile strength alone isn’t enough to predict how materials will handle bending stresses. Plus, we’ll highlight some of the best materials, like carbon fiber and G10 fiberglass, that excel in flexural performance for demanding environments.
In this post, we explore the critical compressive properties of materials that play a pivotal role in ensuring the structural integrity and performance of various components under load-bearing conditions. We delve into key properties such as compressive strength, compressive modulus, and compression set, and how they are evaluated using industry-standard testing methods. Additionally, we highlight real-world applications where these properties are crucial, such as in seals, gaskets, and structural supports.
In this post, we’ll dive into the key tensile properties you’ll find on material data sheets, such as tensile strength, elongation at break, and modulus of elasticity. We’ll also explore how these properties are measured, the standards that guide these measurements, and how various external factors can impact tensile performance. Whether you’re designing a product or selecting materials for a specific use case, this guide will equip you with the knowledge to make informed decisions.
Selecting the right material for sealing applications is a crucial task for engineers, ensuring the durability and effectiveness of seals in various environments. While material data sheets provide valuable insights, applying this theoretical data to real-world scenarios can be challenging. Our blog series, “From Data Sheets to Real World: A Practical Guide to Material Properties for Sealing Products,” addresses this challenge by offering a comprehensive exploration of key material properties and their practical implications.
In this post, we dive into a core principle of material science—understanding stress and strain. Mastering these concepts is crucial for interpreting tensile and compressive properties, enabling engineers to accurately predict how materials will behave under various conditions.
Packer elements are crucial in maintaining well integrity in gas wells, providing reliable seals under extreme conditions. However, CO2 corrosion poses a significant threat to these elements, especially under compressive stress. A recent comprehensive study has given us valuable insights into the performance of hydrogenated nitrile butadiene rubber (HNBR) and nitrile rubber (NBR) in such environments. Here, we summarize the study’s findings and offer recommendations for engineers in the selection and maintenance of packer elements for gas wells.
A frequent question in the Oilfield industry is whether to use Elgiloy or 316 stainless steel for spring energized seals. This post will explore the specific conditions under which Elgiloy is the preferred choice due to its superior resistance to certain corrosive media in oilfield applications.
Hydrogenated Nitrile Butadiene Rubber (HNBR) is renowned for its toughness and resistance to heat, oil, and various chemicals. However, its effectiveness against hydrogen sulfide (H2S) significantly depends on the amount of Acrylonitrile (ACN) content and the mix of fillers, softeners, and curing agents used. This post explores the complex interplay of these factors and their impact on HNBR’s performance in harsh H2S environments.
