Localization Phenomena in Mistuned Assemblies with Cyclic Symmetry Part I: Free Vibrations
(The American Society of Mechanical Engineers (ASME), 1988)An investigation of the effects of small structural irregularities on the dynamics of nearly periodic structures with cyclic symmetry is presented. The system studied may be regarded as a simple ... -
Finite Element Analysis on Modal Parameters of Anisotropic Laminated Plates
(The American Society of Mechanical Engineers (ASME), 1988)This paper is concerned with the finite element technique for predicting the dynamic properties of anisotropic fiber-reinforced composite laminated plates. Considering the effect of transverse shear ... -
Boundary Integral Equation Methods in Eigenvalue Problems in Elastodynamics and Thin Plates

Experimental Diagnosis of Fracture Damage in Structures by the Modal Frequency Method
(The American Society of Mechanical Engineers (ASME), 1988)The present paper used the modal frequency method to diagnose the fracture damage experimentally in simple structures, based on the analytical theory of the spring-loaded “fracture-hinge.” It is ... -
Structural Integrity Monitoring

A New Approach for the Identification of a Regression Locus for Estimating CDF-Failure Equations on Rectified Plots
(The American Society of Mechanical Engineers (ASME), 1987)In estimating the cumulative density function of data, investigators selectively transform the data and their order statistics in order to achieve rectification of the data string. Ordinary ... -
Prediction of Stochastic Endurance Strength
(The American Society of Mechanical Engineers (ASME), 1987)Engineers use fatigue strength modification factors as suggested by Marin in various forms, all of them deterministic. There are advantages to the designer in using these factors in a stochastic ... -
Elastodynamic Radiation From Line Sources Buried in Layered Media Having Periodically Varying Interfaces
(The American Society of Mechanical Engineers (ASME), 1987)We describe here a method for determining the elastodynamic (P and SV waves) radiation characteristics of finite-size sources buried in a horizontally layered medium, having periodically corrugated ... -
Estimation of the Surface Roughness on the Race or Balls of Ball Bearings by Vibration Analysis
(The American Society of Mechanical Engineers (ASME), 1987)This paper describes a vibration-based diagnostic method by estimating the surface roughness on the rotating ring or balls in ball bearings. The surface roughness has been measured by a stylus ... -
The Effects of Modal Coupling on the Acoustic Power Radiation From Panels
(The American Society of Mechanical Engineers (ASME), 1987)The effects of modal coupling on the acoustic power radiated from line forced panels of unit width with s-s (simply supported-simply supported) and c-c (clamped-clamped) end conditions have been ... -
Automated Noninvasive Motion Measurement of Auditory Organs in Fish Using Ultrasound
(The American Society of Mechanical Engineers (ASME), 1987)A scanning underwater, ultrasonic system has been developed to measure the in vivo vibrational amplitude response of fish hearing organs to low-frequency sound. The fish is insonified with a ... -
Estimating Fatigue Due to Cyclic Multiaxial Stress
(The American Society of Mechanical Engineers (ASME), 1987)A new expression similar to the Huber-von-Mises-Hencky criterion for multiaxial stresses, also known as the distortional energy theory, is derived from the second order stress invariants of the ... -
Design with Nonhomogeneous Materials—Part II: Torsion of Thin-Walled Prismatic Bars
(The American Society of Mechanical Engineers (ASME), 1987)Theories have been developed for the torsion of nonhomogeneous thin-walled prismatic bars of open section and thin-walled tubes. The mechanical response of these members has been shown to be ... -
Design with Nonhomogeneous Materials—Part III: Shear Effects in the Bending of Thin-Walled Prismatic Beams
(The American Society of Mechanical Engineers (ASME), 1987)A simple theory, in which longitudinal and shear strains are not coupled, has been developed to account for shear effects in the bending of thin-walled nonhomogeneous prismatic beams. This ... -
Acoustic Radiation From Bending Waves of a Plate
(The American Society of Mechanical Engineers (ASME), 1987)In the commonly used definition of acoustic “radiation efficiency” of a plate, it is assumed that the amplitude of a traveling harmonic wave on the plate is kept constant, independent of the ... -
Design with Nonhomogeneous Materials—Part I: Pure Bending of Prismatic Bars
(The American Society of Mechanical Engineers (ASME), 1987)Because material properties vary from point to point in nonhomogeneous materials, there is some question as to what “properties” are measured in tests such as the tensile test, and how such ... -
Transmission of SH Waves Through a Periodic Array of Elastic Cylinders
(The American Society of Mechanical Engineers (ASME), 1987)The reflection and transmission characteristics of a grating of identical, circular elastic cylinders, arranged periodically in an elastic slab, are investigated. Use is made of a simple approach ... -
