Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Computer Assisted Methods in Engineering and Science, 2019 This treatise collects and reflects the major developments of direct (discrete) variational calculus since the end of the 17th century until about 1990, with restriction to classical linear elastomechanics, such as 1D-beam theory, 2D-plane stress ...

Numerical Exploration of Thermal Shock Resistance in MgO–C Refractories
Advanced Engineering Materials, EarlyView.A mesostructure‐resolved numerical framework is developed to evaluate the thermal shock resistance of MgO–C refractories. By modeling interface debonding under rapid temperature changes and introducing a modified thermal shock parameter that accounts for mesocracks, the study shows how graphite content and aggregate size influence thermal shock ...

Symplectic Model Order Reduction with Non-Orthonormal Bases
Mathematical and Computational Applications, 2019 Parametric high-fidelity simulations are of interest for a wide range of applications. However, the restriction of computational resources renders such models to be inapplicable in a real-time context or in multi-query scenarios.

A general framework for thermodynamically consistent parameterization and efficient sampling of enzymatic reactions. [PDF]
PLoS Computational Biology, 2015 Kinetic models provide the means to understand and predict the dynamic behaviour of enzymes upon different perturbations. Despite their obvious advantages, classical parameterizations require large amounts of data to fit their parameters.

Improved Error Estimates of Solutions in the Linear Theory of Thin Elastic Shells
Engineering Transactions, 1984 DANIELSON [2] has shown that the difference between the classical linear shell theory solution and the solution of the three dimensional elasticity theory is in the L2 norm a quantity of relative order e. In this report that difference is proved to be of

Stress analysis of rotational shaft with a constant angular speed using strain gradient theory [PDF]
International Journal of Advanced Design and Manufacturing Technology, 2012 In classical mechanics, considering Hook’s law stress is a linear function of strain. While in strain gradient theory stress is a function of strain and strain differentials.

Mathematical model for elastic beams with longitudinally variable depth [PDF]
, 2001 In this work we introduce a new mathematical model for elastic beams with a cross-section of constant width and longitudinally variable depth, obtained from the classical three-dimensional linear elasticity problem by using an asymptotic expansion ...
