摘要
Shakedown theory is applied to the determination of plastically admissible ranges of external loads for periodic metal-matrix composites. A link is established between local stress-fields in a representative volume element on the microlevel and admissible stresses on the macrolevel by the use of the homogenisation technique. The developed methodology is applied for illustration to the problem of the best choice of design parameters for a composite.
