A microstructure-sensitive driving force for crack growth

Driving Force for Nucleation of Multi-Component Gas Hydrate

Based on driving force for crystallization of one-component gas hydrate, in this report an expression for the supersaturation for crystallization of multicomponent gas hydrate is derived. Expressions for the supersaturation are obtained in isothermal and isobaric regimes. The results obtained are applied to the crystallization of hydrates of mixtures of methane plus ethane and can apply to ...

A Microstructure-Based Time-Dependent Crack Growth Model for Life and Reliability Prediction of Turbopropulsion Systems

The objective of this investigation was to develop an innovative methodology for life and reliability prediction of hot-section components in advanced turbopropulsion systems. A set of generic microstructure-based time-dependent crack growth (TDCG) models was developed and used to assess the sources of material variability due to microstructure and material parameters such as grain size, activa...

What Is The Driving Force Behind Industrial Development In Iran? Rent Seeking And Labor Exploitation As The Driving Force Of Industrial Growth

A driving force.

Paul B. MacCready has a knack for knowing the difference between the impossible and that which is merely extremely difficult. In the late 1980s, MacCready, founder and CEO of AeroVironment, a company that consults on pollution management and wind energy, figured that a battery-powered automobile could be practical , provided the entire machine was optimized for efficiency. It would have to be e...

Force Sensitive Handles and Capacitive Touch Sensor for Driving a Flexible Haptic-Based Immersive System

In this article, we present an approach that uses both two force sensitive handles (FSH) and a flexible capacitive touch sensor (FCTS) to drive a haptic-based immersive system. The immersive system has been developed as part of a multimodal interface for product design. The haptic interface consists of a strip that can be used by product designers to evaluate the quality of a 3D virtual shape b...
