Dear fellow Mechanicians,We have done this research on couple stress theory which we believe has resolved the problem of indeterminacy in the spherical part of the couple-stress tensor and the appearance of the body couple in the constitutive relation for the force-stress tensor  (Mindlin and Tiersten, 1962).I humbly request you to read the paper and give me your feedback. I believe you would agree this is an important issue in Continuum Mechanics which can open up new frontiers.Sincerely,

Size effects

In this paper that was published a few months ago, we reported the size effects on the elastic modulus and fracture strength of silicon nanowires. In addition, we observed that the silicon nanowires are linear elastic until fracture with a very large fracture strain up to 12%.

The fabrication process for microelectronic devices can have over 300 different processing steps and can take anywhere from six to eight weeks. During this process the wafer substrate must be able to withstand the extreme conditions of manufacturing, since a failure at any step would result in the loss of time and money. The hardness and strength of a wafer must be much greater then the conditions imposed during manufacturing to insure a failure will not occur. Here nanoindnetation is used.
