DOI: 10.1007/s10035-020-01039-5
Abstract: We investigate the conditions leading to large drag force fluctuations in granular materials. The study is based on a set of experimental drag tests, which involve pulling a plate vertically through a cohesionless granular material.… read more here.

DOI: 10.1007/s40571-016-0132-5
Abstract: We discuss a constitutive law for modeling rate-dependent granular flows that has been implemented in smoothed particle hydrodynamics (SPH). We model granular materials using a viscoplastic constitutive law that produces a Drucker–Prager-like yield condition in… read more here.

DOI: 10.1016/j.bpj.2017.03.022
Abstract: The atrial-specific ultrarapid delayed rectifier K+ current (IKur) inactivates slowly but completely at depolarized voltages. The consequences for IKur rate-dependence have not been analyzed in detail and currently available mathematical action-potential (AP) models do not… read more here.

DOI: 10.1016/j.coldregions.2020.103166
Abstract: Abstract The rate-dependent uniaxial compressive behavior of frozen clay soil is strongly affected by its minerals, void ratio, stress history, and pore fluid salinity. Previous studies show that an extremely low deformation rate applied on… read more here.

DOI: 10.1016/j.compscitech.2020.108007
Abstract: Abstract Strain rate dependent characterizations of glass fiber reinforced thermoplastic (LFT) under different multiaxialities show an increasing fracture strain and higher energy absorption capacity if the loading rate rises. The present paper gives a clue… read more here.

Rate-dependent model for simulating the hysteretic behavior of low-yield stress buckling-restrained braces under dynamic excitations

DOI: 10.1016/j.engstruct.2020.111659
Abstract: Abstract Buckling-restrained braces (BRBs) are often idealized with rate-independent simulation models. However, under dynamic loading, BRBs featuring low-yield point steel exhibit rate-dependency that may lead to appreciable amplifications of the BRB forces. This paper proposes… read more here.
