Fatigue and Fracture Mechanics of Structural Metals, Plastics, and Composites

摘要

AFOSR/DOD-URIP funds were used to purchase an Instron computer-controlled mechanical test system for the purpose of evaluating the fatigue and fracture response of metals, plastics, and composites. The FCP Run program provided with the test system has been modified to include differing testing options (constant K sub max and constant K sub mean decreasing K threhold procedure) and incorporate stress intensity factor and compliance calibrations for several additional specimen configurations. Experiments have been conducted with both plastics and metals to confirm the unsefulness of the system and the modifications of the software.
