## Statistical mechanics of a dielectric polymer chain in the force ensemble

Tue, 2021-10-19 12:32 - matthew.grasingerDear colleagues,

We invite you to see the preprint of our new paper "Statistical mechanics of a dielectric polymer chain in the force ensemble" that will appear in Journal of the Mechanics and Physics of Solids. Here we compute the electroelasticity of single polymer chains using both analytical approximations and novel MCMC techniques. Working in the fixed force ensemble facilitates the derivation of the analytical approximations, which are shown to agree well with the MCMC results. This work complements prior work on the statistical mechanics of dielectric polymers chains obtained in a different ensemble. (https://doi.org/10.1016/j.jmps.2021.104658).

## Scientists report solving one of the oldest problems in mechanics

Thu, 2017-07-20 14:16 - Cemal BasaranBeing able to accurately predict the life span of physical bodies, both living and non-living, has been one of humankind’s eternal endeavors. Over the last 150 years, many attempts were made to unify the field of Newtonian mechanics and thermodynamics, in order to create a generalized and consistent theory of evolution of life-span.

## Extreme Particle Shape Effect for Packs of Platonic Solids

Fri, 2015-04-10 23:38 - karelmatousFor centuries, great minds like Kepler, Maxwell and Einstein have investigated the statistical characterization of many-body systems, and implications of small-scale structures on the macroscopic transport and mechanical properties. In this work, an accurate statistical description of heterogeneous particulate materials is computed using novel adaptive interpolation/integration scheme. This statistical information is then utilized within mathematical theories for predicting the overall thermo-mechanical behavior.

## Freely jointed chain

Mon, 2013-02-18 20:45 - Zhigang SuoA single strand of polymer is a chain of a large number of monomers. The monomers are joined by covalent bonds, and two bonded monomers may rotate relative to each other. At a finite temperature, the polymer rapidly changes from one configuration to another. When the two ends of the polymer are pulled by a force, the distance between the two ends changes. The polymer is known as an entropic spring.

## Microcanonical Entropy and Mesoscale Dislocation Mechanics and Plasticity

Mon, 2010-11-08 21:34 - Amit Acharya(Journal of Elasticity, Carlson memorial Volume)

A methodology is devised to utilize the statistical mechanical entropy of an isolated, constrained atomistic system to define the dissipative driving-force and energetic fields in continuum thermomechanics. A thermodynamic model of dislocation mechanics is discussed. One outcome is a definition for the mesoscale back-stress tensor and the symmetric, polar dislocation density-dependent, Cauchy stress tensor from atomistic ingredients.

## Free Energy

Mon, 2009-02-23 14:54 - Zhigang SuoFor a system in thermal contact with the rest of the world, we have described three quantities: entropy, energy, and temperature. We have also described the idea of a constraint internal to the system, and associated this constraint to an internal variable.

## Pressure

Tue, 2007-02-20 13:00 - Zhigang SuoSo far we have been mainly concerned with systems of a single independent variable: energy (node/4878). We now consider a system of two independent variables: energy and volume. A thermodynamic model of the system is prescribed by entropy as a function of energy and volume.

The partial derivatives of the function give the temperature and the pressure. This fact leads to an experimental procedure to determine the function for a given system.

The laws of ideal gases and osmosis are derived. The two phenomena illustrate entropic elasticity.
