Abstract: Plastic behavior is investigated for a material which initially work-hardens, but eventually can have a limiting stress state at which continued straining is possible without increase in stress. ...

Abstract: Sandwich structures composed of two thin sheets separated by a core which can support only transverse shear are both statically and kinematically determinate “in-plane”, allowing in-plane ...

Abstract: Observations of microscale behavior of cast irons indicate that considerable plastic flow occurs between microflaws prior to rupture. Therefore, the plastic limit load for small representative ...

Abstract: It is commonly thought that the limit theorems of ideal plasticity are restricted to perfectly plastic material or structural behavior and to the requirement of no essential change in geometry. ...

Abstract: The problem of determining a limit condition for a composite material in terms of average stresses by limit analysis is incompletely specified, and the limit condition so-obtained may be ...

Abstract: Research performed to develop thermography as a routine rapid flaw detection tool for large composite structures is presented. The externally applied thermal field (EATF) technique is described ...
