Have you ever wondered how materials cope with wear and tear over time? Fatigue testing simulates real conditions, subjecting materials to repeated load cycles, such as those that occur in components and structures on a daily basis. This test is essential for verifying resistance and durability in real situations.

During the process, a sample is subjected to periodic loads in specific machines, allowing the number of cycles until failure occurs to be measured. This data shows how the material behaves under continuous stress.

With this test, it is possible to predict the useful life of the material and detect possible points of failure, helping to optimize projects and reduce maintenance costs.

Versatility and security

Elastomers are polymeric materials with viscoelastic properties, which means they can be stretched and deformed under tension and then return to their original shape when the tension is removed. This unique ability makes these materials extremely versatile and valuable across multiple industries.

In the context of civil and railway construction, elastomers play a crucial role. They are used in large works and railway systems for a series of applications, ranging from shock absorption to vibration isolation. These properties are fundamental to ensuring the safety and adequate performance of structures and systems.

However, to ensure that these elastomers meet the necessary quality and performance standards, it is essential to carry out a series of rigorous tests defined by international Technical Standards. This is where LAEDE – Acoustics and Dynamic and Static Testing Laboratory comes in.

LAEDE, part of IEME Brasil, has extensive experience in high-capacity static and dynamic mechanical testing, which plays a key role in the evaluation and certification of elastomers used in a variety of applications.

The tests carried out by LAEDE include the evaluation of the mechanical and performance properties of materials. This includes quasi-static tests of vertical and shear stiffness, dynamic tests of free and forced vibration, permanent loading, fatigue (mechanical aging) and obtaining the damping coefficient. Additionally, the laboratory is capable of reproducing specific conditions in greenhouse and water environments, which is crucial for testing elastomers in real-world conditions.

The importance of these tests cannot be underestimated. They ensure that elastomers function as expected, providing the necessary shock absorption, vibration isolation and flexibility in various applications. This rigorous assessment also helps identify any wear or degradation over time, ensuring the safety and durability of these materials.

LAEDE is part of the Brazilian Network of Testing Laboratories (RBLE) and is a laboratory accredited by Cgcre in accordance with ABNT NBR ISO/IEC 17025. This means that the tests meet the highest standards of quality and technical competence. Therefore, when choosing LAEDE to carry out these tests, you can be confident that you are working with experienced and certified professionals.
