Strain energy density as a Gaussian process and its utilization in stochastic finite element analysis: application to planar soft tissues
Ankush Aggarwal, Bjørn Sand Jensen, Sanjay Pant +1
Data-based approaches are promising alternatives to the traditional analytical constitutive models for solid mechanics. Herein, we propose a Gaussian process (GP) based constitutiv…
A Bayesian constitutive model selection framework for biaxial mechanical testing of planar soft tissues: application to porcine aortic valves
Ankush Aggarwal, Luke T. Hudson, Devin W. Laurence +2
A variety of constitutive models have been developed for soft tissue mechanics. However, there is no established criterion to select a suitable model for a specific application. Al…
A p-adaptive, implicit-explicit mixed finite element method for reaction-diffusion problems
Mebratu Wakeni, Ankush Aggarwal, Lukasz Kaczmarczyk +4
A new class of implicit-explicit (IMEX) methods combined with a p-adaptive mixed finite element formulation is proposed to simulate the diffusion of reacting species. Hierarchical…
Beyond Newton: a new root-finding fixed-point iteration for nonlinear equations
Ankush Aggarwal, Sanjay Pant
Finding roots of equations is at the heart of most computational science. A well-known and widely used iterative algorithm is the Newton's method. However, its convergence depends…
On improving the numerical convergence of highly nonlinear elasticity problems
Yue Mei, Daniel E. Hurtado, Sanjay Pant +1
Finite elasticity problems commonly include material and geometric nonlinearities and are solved using various numerical methods. However, for highly nonlinear problems, achieving…
Self-assembly of artificial microtubules
Shengfeng Cheng, Ankush Aggarwal, Mark J. Stevens
Understanding the complex self-assembly of biomacromolecules is a major outstanding question. Microtubules are one example of a biopolymer that possesses characteristics quite dist…
