Thin shell torispherical pressure vessel heads are known to exhibit complex elasticplastic deformation and buckling behaviour under static pressure. In pressure vessel Design by Analysis, the designer is required to assess both of these behaviour modes when specifying the allowable static load. The EN and ASME Boiler and Pressure Vessel Codes permit the use of inelastic analysis in design by an...

The process of architectural design aims to define a physical form that will achieve certain functional and behavioral objectives in a particular context. It comprises three distinct, but highly interrelated, operations: (1) Definition of the desired objectives; (2) production of alternative design solutions; (3) evaluation of the expected performances of the solutions and comparing them to the...

This paper describes a dynamically reconfigurable hardware-based computer called the Plastic Cell Architecture (PCA). PCA consists of dualstructured sea-of -cells that consist of a built-in part and a plastic part. The built-in part forms ‘cellular automata’ while the plastic part looks like an SRAM-based FPGA. We detail the design flow especially how to implement logic onto the processing elem...

Metallic auxetic metamaterials are of great potential to be used in many applications because of their superior mechanical performance to elastomer-based auxetic materials. Due to the limited knowledge on this new type of materials under large plastic deformation, the implementation of such materials in practical applications remains elusive. In contrast to the elastomer-based metamaterials, me...
