RISDevelopment of High-Temperature, Interlaminar Tension Test Methodology for Ceramic Matrix Composites
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper was to present how an affordable, high-temperature, interlaminar tension (ILT) strength testing method was explored and developed for ceramic matrix composites (CMCs), leading to development of a diametral-compression ...
Slow Crack Growth of a Pyroceram Glass Ceramic Under Static Fatigue Loading—Commonality of Slow Crack Growth in Advanced Ceramics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An extensive experimental work for Pyroceram™ 9606 glass–ceramic was conducted to determine static fatigue at ambient temperature in distilled water. This work was an extension and companion of the previous work conducted ...
Quantification of Foreign Object Damage and Electrical Resistivity for Ceramic Matrix Composites and Tensile Residual Strength Prediction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: SiCbased ceramic matrix composites (CMC) in turbine engine applications must sustain certain foreign object impacts (FOIs) that might occur in services. Experiments and nondestructive evaluation (NDE) have illustrated good ...
Foreign Object Damage in an Oxide/Oxide Ceramic Matrix Composite Under Prescribed Tensile Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Foreign object damage (FOD) behavior of an N720/alumina oxide/oxide ceramic matrix composite (CMC) was characterized at ambient temperature by using spherical projectiles impacted at velocities ranging from 100 to 350 m/s. ...
Foreign Object Damage Behavior of a Silicon Carbide Fibrous Ceramic Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The response of a silicon carbide (SiC) fibrous ceramic composite to foreign object damage (FOD) was determined at ambient temperature and velocities ranging from 40 to 150 m/s. Target specimens were impacted, at a normal ...
On the Influence of Nonlinear Inertial Forces on the Limit Cycle Oscillations of an Inextensible Plate in a Supersonic Axial Flow
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent results in the literature highlight the impact of nonlinear inertial forces on the post-flutter limit cycle oscillation (LCO) characteristics of highly deflected structures in supersonic axial flow. The current ...
Phenomena of Foreign Object Damage by Spherical Projectiles in EB PVD Thermal Barrier Coatings of Turbine Airfoils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Thermal barrier coatings (TBCs), attributed to their inherent brittleness, are vulnerable to damage by impacting foreign objects when kinetic energy of the objects surpasses certain limits. The damage is termed foreign ...
Fatigue Characteristic Analysis of New ECO7175v1 Extruded Aluminum Alloy
Publisher: American Society of Civil Engineers
Abstract: This paper investigates the fatigue characteristics of a new extruded aluminum 7175, with an experimental composition which uses a magnesium-calcium alloy during the alloying process instead of the standard pure magnesium. ...
Life-Limiting Behavior of an Oxide/Oxide Ceramic Matrix Composite at Elevated Temperature Subject to Foreign Object Damage
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The life-limiting behavior of an N720/alumina oxide/oxide ceramic matrix composite (CMC) was assessed in tension in air at 1200 °C for unimpacted and impacted specimens. CMC targets were subjected to ballistic impact at ...
An Investigation of the End-Notched Flexure and End-Loaded Split Tests Applied to the Mode II Interlaminar Fracture of a SiC/SiC Ceramic Matrix Composite
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Delamination is a common failure mode observed in ceramic matrix composites (CMCs) and occurs as a result of applied interlaminar tensile and shear stresses exceeding the interlaminar strength. As CMCs are further implemented ...
