Key words: residual stress, injection molding, stress analysis
, thermal analysis, polypropylene, glass fibre, warpage
This capability has not been extensively exploited in the past due to the complexity of stress analysis
in highly complex shapes, but with the advancements in finite element analysis (FEA) tools, this design advantage of metalcastings becomes a significant advantage.
The study consisted of a microscopic examination of the samples, review of molecular weight measurements using gel permeation chromatography (GPC), and a design evaluation based on the numerical stress analysis
solutions by finite element analysis (FEA).
Up to now, it was necessary to pass the C-Pack/W results to a "third-party" finite-element stress analysis
(FEA) program from another vendor (interfaces are available for Ansys from Swanson Analysis Systems, Inc.
Robust Speckle Metrology: Techniques for Stress Analysis
The examples they discuss are laser rapid manufacturing, lasers in metal forming, the laser forming of metal foams, the mathematical modeling of laser drilling, the thermal stress analysis
of laser cutting a small diameter hole, modeling and simulating laser welding, and lasers in surface engineering.
ESSENTIALS OF MECHANICAL STRESS ANALYSIS
. Amir Javidinejad.
Writing for advanced undergraduates and beginning graduates in engineering, Claycomb (physics, Houston Baptist U.) introduces electromagnetics and its applications using MATLAB, the numerical computing environment and programming language, and QuickField, a finite element method software package that supports electrostatics, DC and AC conduction, magnetostatics, AC and transient magnetics, steady state and transient heat transfer, and stress analysis
1) originally was developed for solving complex stress analysis
problems for aircraft structures.
Peel stress analysis
. The peel load for initial fracture, which is governed by the maximum peel stress in the fracture region, is of interest to the designer.
Shrinkage data are then converted to nodal force data inside the warpage analysis program, which is analogous to a large-displacement stress analysis
. The warpage analysis program also uses the existing geometries from flow analysis and takes data on mechanical properties of the resin from the resin database.
