Objective
Objectives and content:
Important industries like marine and offshore technology, power generating, nuclear, chemical, process and oil refinement industries operate a large number of safety-critical components. Many advanced structural components must safely function under heavy loading conditions: ship and offshore structures in heavy sea or ship collision, nuclear and chemical reactors, thermal engines, pressure vessels and piping. All these components behave ductile and develop plastic deformations under severe loading or under some normal operating conditions. Consequently the relevant design codes, integrity assessment procedures or classification rules use Limit and Shakedown Analysis (LISA) concepts of plasticity. But they are only developed for idealised structures, which do hardly represent industrial problems of realistic complexity. Idealisations may lead to inferior design and unknown sa estimations show that about 4% of the gross economic product are lost in America and Europe through fracture.
The aim of the proposed research is to reduce or to remove the need for idealised safety and reliability analyses by developing the Finite Element Method (FEM) based LISA concept. Hard numerical problems have restricted its application to mainly academic problems. More recently, promising methods have been proposed for FEM based LISA. It is now the right time to combine and extend the different approaches to develop assessment tools for perfect and for crack-containing industrial structures under complex thermo-mechanical loading. The consortium was chosen to represent the wide scope of methods and range of industries: A research centre and two universities contribute expertise of LISA, the required numerical methods and application to steel structures, fracture mechanics, structural reliability and plant safety. The consortium comprises four industrial partners including a SME and an industrial sub-contractor: a power plant manufacturer and an end-user, a classification society, an FEM supplier, and a testing and consulting company.
