Crush Resistance Testing
Crush resistance testing involves the measurement of a compressive load to a point when a sample deforms, fractures, shatters or collapses. This type of test may be applied to a variety of products including corrugated cardboard, glass, bearings, bricks, concrete, or any sample where crush resistance is important. This is a common test used in packaging design and validation.
Generally, a crush resistance test involves a load limit. The material under test is compressed and compared to the load limit. Maximum load, load at break and work at maximum load are calculated.
