Abstract:
For elastic materials containing fluid-saturated porosity, the pore compressibility is a measure of the deformation of a unit pore volume in response to a change in fluid pressure. Rather than being measured, this quantity has been routinely set equal to an effective solid compressibility, since this equality is exact whenever a single solid component is present. However, we show that the pore compressibility and solid compressibility may be uncorrelated in general. In certain special circumstances they do not even share the same sign. Although thermodynamic and mechanical stability constraint

Abstract:
Negative compressibility is a rare but desirable property whereby a material's crystal structure actually expands in one (negative linear compressibility, NLC) or two (negative area compressibility, NAC) principal directions against application of increasing hydrostatic pressure. The performance of such materials–for use in, for e.g., sensitive interferometric or ferroelectric pressure sensing devices, advanced actuators, or prototype artificial muscle–critically depends on the magnitude of intrinsic negative response. NLC and NAC have been previously reported in a diverse range of materials:

Abstract:
Negative Linear Compressibility (NLC), where a material expands in a given direction when subjected to hydrostatic compression, is a rare elastic property that has received much attention recently, but has yet to be used in practical applications. What are the mechanisms responsible for this property in crystals and man-made structures? Are all mechanisms somehow related to the wine-rack model? Can we find an even simpler and more fundamental elucidation of NLC? Following this mechanistic approach, can we then identify “engineering” materials with NLC? To answer these questions, I have used a

This chapter describes in detail the framework of anisotropic elasticity to introduce exotic elastic and thermoelastic properties that are often prevalent and extreme in MOFs: negative linear compressibility (NLC), negative thermal expansion (NTE) and negative Poisson's ratio (NPR). The complete elastic tensors of 56 MOFs are collated and analysed to reveal that NPR is very common in non-cubic MOF structures, but the mechanisms are not yet clear. This is in contrast to NLC and NTE, which derive from the interplay between rigid, stiff building blocks and compliant joint flexing in ‘wine-rack’ t

It is a common feature of teaching methodologies to divide the content into modules for lectures or book sections. However, these divisions are often not intrinsic to the real problems.

An example of this is the division between capacity and deformability of axially loaded piles, which follows the approach of regulatory manuals dividing stability and serviceability calculations.

These observations may be described by apparent effective stress coefficients significantly larger than one. A possible interpretation is a negative shale stiffness leading to th
