Welded Structures Complex weld shapes and residual stresses require special fatigue considerations for welded structures. The heat from the welding process causes local tensile residual stresses at the weld toe, geometric distortions which lead to additional bending stress and changes in material properties near the weld. In addition, the local geometry along the weld toe varies along its length. Several approaches have been developed to analyze welded structures.

MSC Nastran Multidisciplinary Structural Analysis MSC Nastran is a multidisciplinary structural analysis application used by engineers to perform static, dynamic, and thermal analysis across the linear and nonlinear domains, complemented with automated structural optimization and award winning embedded fatigue analysis technologies, all enabled by high performance computing. Engineers use MSC Nastran to ensure structural systems have the necessary strength, stiffness, and life to preclude failure excess stresses, resonance, buckling, or detrimental deformations that may compromise structural function and safety. MSC Nastran is also used to improve the economy and passenger comfort of structural designs. MSC Nastran may be used to:
Batch and Furnace Operations This seminar is intended to introduce the participants to the fundamental principles of proper batch and furnace operation in order to obtain acceptable glass quality while limiting the occurrence of problems such as color variation, density, seeds, stones, cord, viscosity, thermal expansion and annealing. Participants will also be exposed to the techniques employed to obtain critical physical property measurements as well as an explanation of how to interpret the generated data. Coating Technology This seminar provides a complete explanation of the role of surface coatings in the maintenance of glass surface strength, their application in both the hot end and the cold end as well as solutions to the problems associated with the use of coatings. In addition, the participant will be instructed in desired coating thickness levels and the techniques required to measure these thickness. Cord and Annealing The objective of this seminar is to provide the participant with the capability to make critical decisions regarding the control of cord and annealing stress.
