shrinkage stress

This can lead to shrinkage stress and rarely to marginal gaps and failure.

They are usually caused by high shrinkage stresses, especially on final passes, or by a hot cracking mechanism.

These are generally the result of longitudinal shrinkage stresses acting on weld metal of low ductility.

In most cases shrinkage stresses will exceed the capability of the wood to accommodate them and radial cracks or splits will form.

Precast units should be allowed time to cool, and preferably dry to the point where surface shrinkage stress are minimised, before being transported to the site.

As a result, they are less prone to shrinkage stress and marginal gaps and have higher levels and depths of cure than direct composites.

Control joints are joints placed in concrete to provide for control of initial shrinkage stresses and cracks of monolithic units.

In some instances short beads with light peening with a ball point tool before the bead cools will reduce shrinkage stress and increase the weld density.

Because of this uneven shrinkage characteristic of wood and the resultant development of shrinkage stresses, it is essential that the proper care and techniques are used when wood is seasoned.

His research covered almost every aspect of concrete use in construction and included shrinkage stresses, creeping, and permeability as well as work on indeterminate structures, timber roofs, and curved bracing members.

Actual concrete tensile stresses induced by internal ice formations, thermal gradients, and shrinkage stresses were found to be higher than those used in most designs or allowed in international codes or standards.

Once melted the glass would be blown into vessels or into cylinders which were then opened into sheets for window glass.The final stage is to anneal the finished glass to avoid damage from shrinkage stresses.

If a green log is allowed to dry it will develop circumferential shrinkage stresses, not only because it will dry first at the outside but also because as drying progresses the circumferential shrinkage will be greater than the radial shrinkage.
