RISA Damage Mechanics-Based Fatigue Life Prediction Model for Solder Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A thermomechanical fatigue life prediction model based on the theory of damage mechanics is presented. The damage evolution, corresponding to the material degradation under cyclic thermomechanical ...
Contact Stresses in Multilayered Strands Under Tension and Torsion1
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: First, an attempt is made to experimentally test the validity of the linear deformation derivative results earlier developed for the multilayered wire-rope strands under tension and torsion. The ...
Enhancement of Methane-Air Mixing Using Shock and Expansion Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unified model of gaseous fuel and air mixing is applied here to study the use of shock waves for enhancement of mixing between methane and air. The model uses fuel mass fraction within ...
Computationally Efficient Micromechanical Models for Woven Fabric Composite Elastic Moduli
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents two newly developed micromechanical models for the analysis of plain weave fabric composites. Both models utilize the representative volume cell approach. The representative ...
Aerothermal Investigations of Mixing Flow Phenomena in Case of Radially Inclined Ejection Holes at the Leading Edge
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A leading edge cooling configuration is investigated numerically by application of a three-dimensional conjugate fluid flow and heat transfer solver, CHT-flow. The code has been developed at the ...
Influence of Tooth Profile Modification on Helical Gear Durability
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonlinear finite element contact mechanics model of a helical gear pair was used to study the effect of intentional tooth profile modifications on durability of helical gear pairs. Both ...
Some Pitfalls of Simplified Modeling for Viscoelastic Sandwich Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is commonplace in academia to base models of constrained-layer damping treatments on the assumption that the facesheets displace identically during transverse vibrations. This assumption is ...
A Special Theory of Biphasic Mixtures and Experimental Results for Human Annulus Fibrosus Tested in Confined Compression
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite deformation mixture theory is used to quantify the mechanical properties of the annulus fibrosus using experimental data obtained from a confined compression protocol. Certain constitutive ...
