Call for Abstract Submission in USNC/TAM 2022-MS 308, Computational Fracture, Fatigue and Damage Modeling
Dear Fellow Mechanicians,
Cordially inviting you to submit an abstract for the upcoming USNC/TAM 2022, in session named as -"Computational Fracture, Fatigue and Damage Modeling"; we are encouraging (not limited to) research related to new method development to understand the fracture, damage and fatigue behavior in complex engineering materials such as soft polymers, composites, biological materials etc. Kindly consider submitting an abstract before the deadline of December 18, 2021.
Universal Deformations in Inhomogeneous Isotropic Nonlinear Elastic Solids
Universal (controllable) deformations of an elastic solid are those deformations that can be maintained for all possible strain-energy density functions and suitable boundary tractions. Universal deformations have played a central role in nonlinear elasticity and anelasticity. However, their classification has been mostly established for homogeneous isotropic solids following the seminal works of Ericksen. In this paper, we extend Ericksen's analysis of universal deformations to inhomogeneous compressible and incompressible isotropic solids.

Postdoc fellowship available at BUAA, China
A two-year/three-year fellowship named as the Hundred-Talent Postdoc Fellowship is available at Beihang University. Beihang University, also known as Beijing University of Aeronautics and Astronautics (BUAA), has always been ranked No. 1 in Aerospace Engineering among all the universities in China. Our research group led by Professor Leiting Dong is seeking talented and motivated candidates to work on the development of state-of-the-art computational mechanics methods and their applications on the analysis and design of complex engineering structures.

On the Interaction of Viscoelasticity and Waviness in Enhancing the Pull-Off Force in Sphere/Flat Contacts
Motivated by roughness-induced adhesion enhancement (toughening and strengthening) in low modulus materials, we study the detachment of a sphere from a substrate in the presence of both viscoelastic dissipation at the contact edge, and roughness in the form of a single axisymmetric waviness. We show that the roughness-induced enhancement found by Guduru and coworkers for the elastic case (i.e. at very small detachment speeds) tends to disappear with increasing speeds, where the viscoelastic effect dominates and the problem approaches that of a smooth sphere.
