Dear Researchers,  

I am a research student, "Surface modification of materials" is my research topic. I joined your site to discuss the crack propagation during thin film deposition.

 It seems that within the field of fracture mechanics, some authors use "fracture" to refer to the mechanism of creating new surfaces within a body by breaking the material bonds and reserve the word "crack" for the sharp-tipped discontinuity that results from fracture of a brittle material. But it does not appear that this distinction is followed consistently throughout the literature, and perhaps different research areas within the fracture mechanics field use the two words in different ways.

It may be well known to researchers on ferroelectrics that tetragonal ferroelectric ceramics, such as BaTiO₃, Ti-rich lead titanate zirconate (PZT), are difficult to pole even using a high DC field with long holding time. While the rhombohedral PZT or PZT near the morphotropic phase boundary (MPB) are easy to pole, especially the latter. Why?

The post doctoral fellow will be engaged in research on the mechanics of hydraulic fracturing of rock. The primary aim of this project is to investigate, using a novel approach for experimentation spanning laboratory and field scales, the effect of fracture size on the energy required for fracture extension in rock.

Information in Imechanica is a little dispersed it is good in its present form but is it possible to categorization of information more?

ADVANCED CALL FOR PROPOSALS: IUTAM SYMPOSIUM and INSTRUCTIONAL SUMMER SCHOOLS for 2010 and 2011 (Proposals due no later than January 15, 2008)

The United States National Committee on Theoretical and Applied Mechanics (USNC/TAM) seeks proposals from U.S. authors and institutions to host IUTAM (International Union of Theoretical and Applied Mechanics) Symposia or IUTAM Instructional Summer Schools in 2010 or 2011.

On June 17-20, 2008 the Inaugural Conference of the American Academy of Mechanics will be hosted in New Orleans, Louisiana. Following this conference this event will be hosted in the USA every four years to coincide with the ICTAM conference. This meeting will help the mechanics communities with applications in solids, fluids, bio, etc. to interact and set new challenging concepts and refinements in the existing areas of Mechanics.
