Introduction Quasi-brittle fracture is a failure characteristic for some important structural materials.
These are brittle materials that have some tolerance to damage and include concrete, polygranular graphite, ceramic-matrix composites, geological rocks and bio-medical materials.
The mechanical properties of engineering materials are usually characterized in uniaxial tension testing by applying quasi-static loads to standardized specimens.

Introduction At present, there are many kinds of high-strength steel materials [1] in China, but the quality of steel products is irregularity, and there is still a great gap in the development and application of the material compared with that in other countries.
Among various kinds of high-strength material, High-strength Heat-treated Steel [1,3,4] is a new material with high strength and high performance.

Virgin Archipelago was entirely built with recycled materials.
The European hotel designers advocate using locally produced materials in order to reduce energy consumption and environmental damage because of long-distance transport.
Meanwhile, in the lobby, restaurant, toilet and guest rooms, managers paste green notices, and other promotional materials to encourage green consumption.
Government should reward the hotels which use energy-saving building materials, water reuse system and waste recycle system.

At present, electrochemical machining (ECM) has been developed as a main method for machining difficult-to-cut materials and shaping complicated contours and profile.
Being a non-mechanical metal removal process, ECM is capable of machining any electrically conductive materials with high stock removal rates regardless of their mechanical properties, such as hardness, elasticity and brittleness.
