Construction of bounds on the elastic moduli of isotropic multicomponent materials which involve three-point correlation parameters. We use numerical methods to study several representative material models. Construction of three-point correlation bounds on the effective elastic shear modulus of composite materials and applications of the bounds are given to some composites.
Innovation in engineering often means the clever use of a new material - new to a
particular application, but not necessarily (although sometimes) new in the sense of
‘recently developed’. Plastic paper clips and ceramic turbine-blades both represent
attempts to do better with polymers and ceramics what had previously been done well
with metals. And engineering disasters are frequently caused by the misuse of
In the latest years graphene based research has witnessed a tremendous
explosion. This two dimensional ‘‘dream’’ material has come into the main spotlight of fundamental and applied research in diverse nano-science fields, but
surprisingly rapidly, it has also attracted the interest of major stakeholders in the

Temperature- and thickness-dependent elastic moduli of polymer thin films
Zhimin Ao*, Sean Li
Abstract The mechanical properties of polymer ultrathin films are usually different from those of their counterparts in bulk. Understanding the effect of thickness on the mechanical properties of these films is crucial for their applications. However, it is a great challenge to measure their elastic modulus experimentally with in situ heating.
