A generic relational database of materials with a strength modeling tool

摘要

A relational web driven database accompanied by a strength modeling tool has been developed to provide a more generic and flexible Information Technology (IT) tool that will enable someone to have fast internet access to strength and other useful properties of a wide range of structural natural or artificial damageable materials. Since many structural plain or composite materials are usually involved in every geotechnical engineering subsurface or surface geostructures (e.g. bolted or shotcreted rock slopes and tunnels, compensation grouting, steel or glass reinforced plastic tendons in soils, retaining walls and wooden piles in contact with soils etc), the following five classes of engineering structural materials are considered: porous and pressure sensitive materials like, (1) rocks and soils, (2) concretes and ceramics as well as (3) woods, and crystalline and ductile materials such as (4) metals or alloys, and amorphous materials like (5) glasses.
