What is Bending Stress and Flexural Strength Rail Testing at Element?

Bending stress and flexural strength testing evaluates how rail materials and components respond to applied forces. One key test is slow bend testing, which validates concrete tie strength and rail weld integrity. Another is cyclic fatigue testing, which demonstrates the ability of rail and integrated fastening systems to withstand repeated loads. At Element, we perform comprehensive rail testing for both slow bend and dynamic and static cyclic fatigue, helping you select materials with optimal strength and flexibility characteristics for the next generation of rail technology.

Frequently asked questions

How is slow bend testing performed for rail weld integrity?

Using 5 ft (1.52 m) sections of rail, we focus bending stress on the center of the weld up to 750 kips. This 4-point flexural testing is critical for determining weld integrity. After testing, if the weld hasn't completely sheared, we examine the rail for cracks and surface defects, and if needed, immediately perform multiple industry-specific metallurgical tests to determine the root cause of any failures.

What makes Element's fatigue testing capabilities unique?

Our fatigue testing uses a one-of-a-kind train simulator specifically designed for AREMA Chapter 30 section 4.9 sub-section 2.7 Test 6. This allows us to test fully assembled sections of railroads for rolling fatigue simulation with static and dynamic testing up to 120 kips. Our specialized test frames can test virtually any rail component, from individual rails to complete fastening systems, providing the most accurate simulations available in the industry.
