Multiphase Differential Scheme for Effective Properties of Magnetoelectroelastic Composite Materials
(The American Society of Mechanical Engineers (ASME), 2017)The differential scheme is extended to predict the effective properties of multiphase magnetoelectroelastic composite materials. The prediction of effective properties is done gradually by adding a series of incremental ... -
A Numerical Method for Stress Concentration Problems of Infinite Plates With Many Circular Holes Subjected to Uniaxial Tension
(The American Society of Mechanical Engineers (ASME), 1974)The boundary collocation method using the general form of the stress function is proved to be available for the problems of stress concentration in infinite plates with many circular holes. ... -
The Optimal Column
(The American Society of Mechanical Engineers (ASME), 1974)A new numerical search algorithm is presented which is employed to determine optimum shapes for pin-ended columns having elastic behavior. The search algorithm utilizes a gradient search scheme ... -
Stability Conditions in Quasi-Static Crack Propagation for Constant Strain Energy Release Rate
(The American Society of Mechanical Engineers (ASME), 1974)Measurement of valid fracture toughness of engineering materials and design assurance of quasi-static crack growth in structures before the onset of fracture instability are the important factors ... -
Bulging Rupture of a Superplastic Sheet
(The American Society of Mechanical Engineers (ASME), 1974) -
Subsequent Yield Surfaces for Annealed Mild Steel Under Dead-Weight Loading: Aging, Normality, Convexity, Corners, Bauschinger, and Cross Effects
(The American Society of Mechanical Engineers (ASME), 1974)After initial yielding of one to five percent small-offset multiple-probe yield curves were determined under combined axial-torsion loading for six tubular specimens. Subsequent yield curves were ... -
A Note on Equivalence of the Postulates of Isotropic Hardening
(The American Society of Mechanical Engineers (ASME), 1974) -
The Effect of Reinforcements on the Slow Stable Tear and Catastrophic Failure of Thin Metal Sheet
(The American Society of Mechanical Engineers (ASME), 1974)To determine the role of the reinforcement on the mechanics of crack arrest and residual strength of reinforced flat panels, both analytical and experimental work was conducted. Fracture tests ... -
The Effect of Slow-Constant Strain Rates on the Tensile Properties of Selected Alloys at Room and Elevated Temperatures
(The American Society of Mechanical Engineers (ASME), 1974)Tensile tests were performed at constant strain rates from 10−2 to 10−5 min−1 on 5454-O and 1100-O aluminum alloys, A515 Grade 70 steel and B166 nickel alloy at room temperature and at ... -
Highlights of a Recent International Conference on Creep and Fatigue

Cells on Porous Substrates In Vitro and In Vivo
(The American Society of Mechanical Engineers (ASME), 1974)Disaggregated cells of kidney, lung and liver of 14-day-old chick embryos were cultivated in vitro on several open-pore, organic-polymer sponges and on one gelatin sponge; in some cases this ... -
A General Statistical Model for Random Fatigue
(The American Society of Mechanical Engineers (ASME), 1974)A general statistical model for fatigue under stationary random gaussian stress is presented. This phenomenological model requires only a limited amount of data from fatigue tests in which ... -
The Influence of Simulated Service Exposure on the Rupture Strengths of Grade 11, Grade 22, and Type 304 Steels
(The American Society of Mechanical Engineers (ASME), 1974)High temperature exposures were carried out to simulate long-time service. Rupture curves for exposed Grade 11 and Grade 22 steels did not exhibit the instabilities characteristic of the unused ... -
Extrapolation of Rupture Data for Type 304 (18Cr-10Ni), Grade 22 (2-1/4Cr-1Mo), and Grade 11 (1-1/4Cr-1/2Mo-3/4Si) Steels
(The American Society of Mechanical Engineers (ASME), 1974)Methods for determining 100,000 hr rupture strengths for setting Code stresses were evaluated critically. Using available data for Type 304, Grade 22, and Grade 11 steels, techniques were examined ... -
Empirical Equations for Describing the Strain-Hardening Characteristics of Metals Subjected to Moderate Strains
(The American Society of Mechanical Engineers (ASME), 1974)The strain-hardening characteristics of a metal have often been described by a power function which employs a work-hardening exponent, “n.” Usually the material is assumed to be rigid to the ... -
Forces Produced by Ground Contact Rotational Orthotic Devices
(The American Society of Mechanical Engineers (ASME), 1974)The correction of lower extremity rotational deformities, such as tibial and femoral torsion, requires the application of derotational forces. One method of applying such rotational forces during ... -
Application of the CO2 Laser to Thermal Properties Measurements in Biomaterials
(The American Society of Mechanical Engineers (ASME), 1974)The CO2 laser provides radiation that is strongly absorbed and only weakly back-scattered by high water-content materials, such as biological tissue. Several methods can be employed to obtain ... -
Notch Sensitivity, Mechanical, and Microstructural Characteristics of TD-NiCr at Elevated Temperatures
(The American Society of Mechanical Engineers (ASME), 1974)Tensile and creep-rupture tests were conducted for smooth and sharp edge-notched specimens of 0.015-in. (0.38 mm) thick TD-NiCr sheet at 1000 to 1800 deg F (538–982 deg C). The dislocation ... -
