Modeling History Dependent Heating of Viscoelastic Polymers under Harmonic Excitation

N. Vasios¹, N. H. Elabbasi¹, J. S. Bergstrom¹
¹Veryst Engineering, LLC., Needham, MA, USA

Soft lossy viscoelastic polymers can dissipate significant amounts of energy in the form of heat when subjected to dynamic mechanical stimuli. As a result, structures comprised of such lossy materials may heat up considerably when excited by loads at a frequency that approaches one of ... En savoir plus

COMSOL in a New Tensorial Formulation of Non-Isothermal Poroelasticity

A. Mario-Cesar Suarez[1], and V. Fernando Samaniego[2]

[1]Faculty of Sciences, Michoacan University, Morelia, Mich., Mexico
[2]Faculty of Engineering, National University of Mexico, Mexico City, Mexico

The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... En savoir plus
