In-plane shear performance statistics of 2D-C/SiC composites and its B-basis value of strength

Cailiao gongcheng, 2019
The distribution of in-plane shear modulus and strength of 2D-C/SiC composites, and its B-basis value of strength were studied by testing thirty Iosipescu specimens under shear load. The distribution and parameters about in-plane shear properties of 2D-C/

Effect of span length on bending strength and Weibull modulus of sintered alumina bar [PDF]

, 2011
The present study was undertaken to evaluate the bending strength of alumina both as a function of sintering temperature and span length. The fracture strength data was calculated on relatively a large number of samples for each data point (14).

Electric-field-induced stress relaxation in alpha-phase poly(vinylidene fluoride) films

, 2013
The relationship between elastic fatigue and electrical cyclic loading in alpha-phase poly(vinylidene fluoride) films has been investigated. Our experimental studies have shown that the electric-field-induced fatigue behavior can be described by a stress

Comparison of two methods of fatigue testing bone cement [PDF]

, 2009
Two different methods have been used to fatigue test four bone cements. Each method has been used previously, but the results have not been compared. The ISO 527-based method tests a minimum of 10 samples over a single stress range in tension only and ...

Failure Probability Evaluation of GIL Tri‐Post Insulators Under Electromechanical Stresses

High Voltage, EarlyView.
ABSTRACT Based on the energy theory, this paper proposes an evaluation method for the breakdown failure probability of the tri‐post insulator in a gas‐insulated metal‐enclosed transmission line (GIL). Various internal defects, vector forces and torque forces were considered, along with the application of an AC voltage.

The Breakdown and Self‐Clearing Performance During the Energy Harvesting Process of Dielectric Elastomer Generators Using Single‐Walled Carbon Nanotubes Electrodes

High Voltage, EarlyView.
ABSTRACT For dielectric elastomer generators (DEG), electrical breakdown is the main failure mode during their working cycle. The application of self‐clearing electrodes is of great significance to avoid a single breakdown leading to the failure of the entire generator.

Risk estimation for LCF crack initiation

, 2013
An accurate risk assessment for fatigue damage is of vital importance for the design and service of today's turbomachinery components. We present an approach for quantifying the probability of crack initiation due to surface driven low-cycle fatigue (LCF)
