Ultimate Tensile Strength
What it is, how to measure it, and why it matters
Ultimate tensile strength (UTS) is a critical property used to determine how materials behave under tension. It defines the maximum stress a material can withstand before breaking.

Compression
Compression testing is a way of determining how something will react when a compressive force is applied to it. It typically involves measuring the relationship between the applied force and how much the object deforms.
It is performed to:

Accessory
Compression Plate, Vented by Holes & Cone, 50 mm, 5-16 UNC
432-348
Vented compression plates are ideal for top-load/crush testing of containers such as PET bottles.
Holes in the plate allow the passage of air to ensure that air inside the bottle is not compressed thereby falsifying the true measurement of the top-load…
