RISResidual Stress Calculation of Hydraulic Autofrettage Thick-Walled Tube Based on a Revised Kinematic Hardening Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The current theoretical calculation methods for autofrettage of thick-walled tube do not adequately consider the change in the stress–strain relationship of the material with the maximum loading strain. This deficiency has ...
A Strongly Coupled Fluid Structure Interaction Solution for Transient Soft Elastohydrodynamic Lubrication Problems in Reciprocating Rod Seals Based on a Combined Moving Mesh Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Soft elastohydrodynamic lubrication (EHL) problems widely exist in hydraulic reciprocating rod seals and pose great challenges because of high nonlinearity and strong coupling effects, especially when the EHL problems are ...
Neural Network Direct Adaptive Control Strategy for a Class of Switched Nonlinear Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper deals with the adaptive neural network (NN) switching control problem for a class of switched nonlinear systems. Radial basis function (RBF) NNs are utilized to approximate the unknown switching control law term ...
Off-Equilibrium Linearization-Based Control of Nonlinear Time-Delay System and Application to a Turbofan Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Turbofan engines exhibit pronounced nonlinearity due to component characteristics and thermal processes, necessitating linearization to connect engine control with linear control theory. Off-equilibrium linearization offers ...
Study on the Microstructure Evolution and Mechanical Properties of Cu/Cu41Sn11/Cu Solder Joint During High-Temperature Aging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper focused on the changes in microstructure and mechanical properties of the full Cu41Sn11 solder joint (Cu/Cu41Sn11/Cu) during isothermal aging at 420 °C. It was motivated by potential applications of Cu–Sn ...
