Kinematic Calibration of Robotic Manipulators
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A kinematic calibration model for serial robotic manipulators is presented. This model is based on the zero position analysis method, and is not prone to the difficulties encountered in case ...
Constructing Exact Dynamic Elasticity Solutions for Axisymmetrically Deformed Plates From Classical Plate Theory Solutions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses the question of how to assess the errors made when the exact three-dimensional linear elasticity solution for the axisymmetric dynamic deformation of an elastic plate is ...
Process Induced Stresses of a Flip-Chip Packaging by Sequential Processing Modeling Technique
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a nonlinear finite element framework was established for processing mechanics modeling of flip-chip packaging assemblies and relevant layered manufacturing. In particular, topological ...
Constitutive Modeling of Polymer Films From Viscoelasticity to Viscoplasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A unified constitutive model for polymer films is proposed with viscoelastic characterization at small deformation and viscoplastic characterization at large deformation based on molecular chain ...
A Damage Coupling Framework of Unified Viscoplasticity for the Fatigue of Solder Alloys
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A damage coupling framework is proposed with a unified viscoplastic constitutive model for the fatigue life prediction of solder alloys, including a consistent and systematic procedure for the ...
Creep Behavior of a Flip-Chip Package by Both FEM Modeling and Real Time Moiré Interferometry
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the creep behavior of a flip-chip package under a thermal load was investigated by using nonlinear finite element technique coupled with high density laser moiré interferometry. ...
Investigation of a New Lead Free Solder Alloy Using Thin Strip Specimens
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The thermomechanical behaviors of a new lead free solder and eutectic 63Sn37Pb are investigated in this paper. A series of tests including tensile, creep, and fatigue, are carried out on a ...
Societal Impacts of a Complete Street Project in a Mixed Urban Corridor: Case Study in Pittsburgh
Publisher: ASCE
Abstract: Complete streets facilitate multimodal travel by improving both transportation access and safety by emphasizing the user, not the automobile. This case study evaluates the impacts of a complete street retrofit on a mixed ...
