Quantification of lubrication and particle size distribution effects on tensile strength and stiffness of tablets
Sonia M. Razavi, Marcial Gonzalez, Alberto M. Cuitiño
We adopt a Quality by Design (QbD) paradigm to better control the mechanical properties of tablets. To this end, the effect of particle size distribution, lubricant concentration,…
General and mechanistic optimal relationships for tensile strength of doubly convex tablets under diametrical compression
Sonia M. Razavi, Marcial Gonzalez, Alberto M. Cuitino
We propose a general framework for determining optimal relationships for tensile strength of doubly convex tablets under diametrical compression. This approach is based on the obse…
Efficient and robust constitutive integrators for single-crystal plasticity modeling
S. N. Kuchnicki, A. M. Cuitino, R. A. Radovitzky
Simulations of the dynamic deformations of metal samples require elastic-plastic constitutive updates of the material behavior to be performed over a small time step between update…
An Exactly Solvable Phase-Field Theory of Dislocation Dynamics, Strain Hardening and Hysteresis in Ductile Single Crystals
M. Koslowski, A. M. Cuitiño, M. Ortiz
An exactly solvable phase-field theory of dislocation dynamics, strain hardening and hysteresis in ductile single crystals is developed. The theory accounts for: an arbitrary numbe…
Two-phase densification of cohesive granular aggregates
Gustavo Gioia, Alberto M. Cuitino
When poured into a container, cohesive granular materials form low-density, open granular aggregates. If pressed upon with a ram, these aggregates densify by particle rearrangement…
A Multiscale Approach for Modeling Crystalline Solids
A. M. Cuitino, L. Stainier, G. Wang +4
In this paper we present a modeling approach to bridge the atomistic with macroscopic scales in crystalline materials. The methodology combines identification and modeling of the c…
A Micromechanical Model of Hardening, Rate Sensitivity and Thermal Softening in BCC Single Crystals
Laurent Stainier, Alberto M. Cuitino, Michael Ortiz
The present paper is concerned with the development of a micromechanical model of the hardening, rate-sensitivity and thermal softening of bcc crystals. In formulating the model we…
Folding Energetics in Thin-Film Diaphragms
Gustavo Gioia, Antonio DeSimone, Michael Ortiz +1
We perform experiments on thin-film diaphragms to show that the folding patterns of anisotropically compressed diaphragms are strikingly different from those of isotropically compr…
