摘要
En 中文
The paper provides an overview of the current status of the COSSAN (TM) [Institute of Engineering Mechanics, Leopold-Franzens University, Innsbruck, Austria, EU. COSSAN. Computational stochastic structural analysis, User's Manual, Part B, 2001; Part A, 1996] software developed at the Institute of Engineering Mechanics of the Leopold Franzens University, Innsbruck, Austria, EU. Two options provided by COSSAN (TM) are described: (1) A 'Stand Alone Tool Box' which is an event driven modular general purpose code and (2) the 'Third Party Communication Tools' which allow to employ deterministic Third Party (FE) codes for stochastic analysis without the need to access and modify the third party source code. The Stand Alone Tool Box covers a fairly wide field of stochastic methods including various sampling techniques, random fields, fatigue analysis, reliability based optimization, random vibration, Monte Carlo simulation and FE-analysis. The Third Party Communication Tools are designed to extend existing deterministic FE-codes for considering uncertainties and consequently perform stochastic analyses using methods based on Monte Carlo procedures.
