Modelling Material Injection Into Porous Structures Under Non-isothermal Conditions
Jan-Sören L. Völter, Zubin Trivedi, Andreas Boger +2
In this work, the Theory of Porous Media (TPM) is employed to model percutaneous vertebroplasty, a medical procedure in which acrylic cement is injected into cancellous vertebral b…
PerSival: Neural-network-based visualisation for pervasive continuum-mechanical simulations in musculoskeletal biomechanics
David Rosin, Johannes Kässinger, Xingyao Yu +3
This paper presents a novel neural network architecture for the purpose of pervasive visualisation of a 3D human upper limb musculoskeletal system model. Bringing simulation capabi…
Rheological Analysis and Evaluation of Measurement Techniques for the Curing Polymethylmethacrylate Bone Cement in Vertebroplasty
Zubin Trivedi, Jacek K. Wychowaniec, Dominic Gehweiler +6
Vertebroplasty is a minimally invasive surgical procedure used to treat vertebral fractures, which conventionally involves injecting polymethylmethacrylate (PMMA) bone cement into…
Low-dimensional Data-based Surrogate Model of a Continuum-mechanical Musculoskeletal System Based on Non-intrusive Model Order Reduction
Jonas Kneifl, David Rosin, Oliver Röhrle +1
In recent decades, the main focus of computer modeling has been on supporting the design and development of engineering prototyes, but it is now ubiquitous in non-traditional areas…
High-density magnetomyography is superior to high-density surface electromyography for motor unit decomposition: a simulation study
Thomas Klotz, Lena Lehmann, Francesco Negro +1
Objective: Studying motor units (MUs) is essential for understanding motor control, the detection of neuromuscular disorders and the control of human-machine interfaces. Individual…
A continuum mechanical porous media model for vertebroplasty: Numerical simulations and experimental validation
Zubin Trivedi, Dominic Gehweiler, Jacek K. Wychowaniec +4
The outcome of vertebroplasty is hard to predict due to its dependence on complex factors like bone cement and marrow rheologies. Cement leakage could occur if the procedure is don…
Time-periodic steady-state solution of fluid-structure interaction and cardiac flow problems through multigrid-reduction-in-time
Andreas Hessenthaler, Robert D. Falgout, Jacob B. Schroder +3
In this paper, a time-periodic MGRIT algorithm is proposed as a means to reduce the time-to-solution of numerical algorithms by exploiting the time periodicity inherent to many app…
A Class of Analytic Solutions for Verification and Convergence Analysis of Linear and Nonlinear Fluid-Structure Interaction Algorithms
Andreas Hessenthaler, Maximilian Balmus, Oliver Röhrle +1
Fluid-structure interaction (FSI) problems are pervasive in the computational engineering community. The need to address challenging FSI problems has led to the development of a br…
Decoding the Rejuvenating Effects of Mechanical Loading on Skeletal Maturation using in Vivo Imaging and Deep Learning
Pouyan Asgharzadeh, Oliver Röhrle, Bettina M. Willie +1
Throughout the process of aging, deterioration of bone macro- and micro-architecture, as well as material decomposition result in a loss of strength and therefore in an increased l…
Multilevel convergence analysis of multigrid-reduction-in-time
Andreas Hessenthaler, Ben S. Southworth, David Nordsletten +3
This paper presents a multilevel convergence framework for multigrid-reduction-in-time (MGRIT) as a generalization of previous two-grid estimates. The framework provides a priori u…
