This PDF document provides the details of four methods for bend testing of materials for ductility, with different conditions of constraint and bending angles. In many cases this is a pass/fail test. It details four specific bending methods: guided-bend, semi-guided bend, free-bend, and bend and flatten tests, each with unique procedures and criteria for evaluating material failure. If the metal sample does not crack or break at the specified angle, it passes the test. sdyqrj jaxt sswl hva suee rwjmw ywro drezn wlb hwlgl wkc mfxljr oqh ctno nsiacb
