Size effects in materials due to microstructural and dimensional constraints: a comparative review
  • E. Arzt
  • Materials Science
  • 9 October 1998
Abstract Effects of size on predominantly mechanical properties of materials are reviewed at a first-order level. Microstructural constraints, e.g. due to second-phase particles and grain boundaries,Expand

  • Materials Science
  • 1 October 1982
Abstract The densification of spherical polders by cold compaction, hot-isostatic pressing and sintering can be described in terms of the shrinkage of the Voronoi cells associated lith the initialExpand

Resolving the nanoscale adhesion of individual gecko spatulae by atomic force microscopy
Animals that cling to walls and walk on ceilings owe this ability to micron and nanoscale attachment elements. The highest adhesion forces are encountered in geckoes, which have developed intricateExpand

Adhesion of bioinspired micropatterned surfaces: effects of pillar radius, aspect ratio, and preload.
Inspired by biological attachment systems, micropatterned elastomeric surfaces with pillars of different heights (between 2.5 and 80 microm) and radii (between 2.5 and 25 microm) were fabricated.Expand

Local mechanical properties of the head articulation cuticle in the beetle Pachnoda marginata (Coleoptera, Scarabaeidae)
SUMMARY Insect exoskeleton (cuticle) has a broad range of mechanical properties depending on the function of a particular structure of the skeleton. Structure and mechanical properties of theExpand

Effects of contact shape on the scaling of biological attachments
Adhesion of biological systems has recently received much research attention: the survival of organisms ranging from single cells and mussels to insects, spiders and geckos relies crucially on theirExpand

Contact shape controls adhesion of bioinspired fibrillar surfaces.
Following a recent bioinspired paradigm, patterned surfaces can exhibit better adhesion than flat contacts. Previous studies have verified that finer contact structures give rise to higher adhesionExpand

Adhesion design maps for bio-inspired attachment systems.
Fibrous surface structures can improve the adhesion of objects to other surfaces. Animals, such as flies and geckos, take advantage of this principle by developing "hairy" contact structures whichExpand

Practical applications of hotisostatic Pressing diagrams: Four case studies
The construction of mechanism maps for hot-isostatic pressing is described. Maps are constructed for a number of materials of commercial and scientific interest: a tool steel, a superalloy, Al2O3,Expand
