RISA New Approach to Evaluate Fracture Toughness of Structural Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new method, designated as Spiral Notch Torsion Test (SNTT), is developed recently to measure the intrinsic fracture toughness (KIC) of structural materials. The SNTT overcomes many of the ...
A Technique to Achieve Uniform Stress Distribution in Compressive Creep Testing of Advanced Ceramics at High Temperatures
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A technique to achieve stable and uniform uniaxial compression is offered for creep testing of advanced ceramic materials at elevated temperatures, using an innovative self-aligning load-train ...
Predictions of Tensile Behavior and Strengths of a Si3N4 Ceramic at High Temperatures Based on a Viscoplastic Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tensile deformation and rupture behavior were simulated using a viscoplastic model developed recently. The model was formulated based on the state variable approach, which provides flexibility and ...
