自動控制理論是人類在了解自然和改造自然的過程中逐漸形成的一門學(xué)科。簡單反饋控制的最早應(yīng)用,可以追溯到古代亞歷山大時期的克泰希比斯水鐘,它就是利用反饋原理來調(diào)節(jié)流量的。19世紀(jì)中葉,J.C.麥克斯威爾對具有調(diào)速器的蒸汽機(這也利用了反饋原理來調(diào)速)系統(tǒng)進(jìn)行了穩(wěn)定性的研究。20世紀(jì)20年代,布萊克、奈奎斯特和波德在貝爾實驗室的一系列研究工作奠定了經(jīng)典自動控制(反饋)的理論基礎(chǔ)------

ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the Mechanical Engineering at Glasgow Universtity. The software which can transfer data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.
