Numerical analysis of damage and failure behavior of concrete

International journal of damage mechanics, 2020
The paper discusses an anisotropic continuum damage model for concrete and its numerical implementation into a finite element program to provide an efficient approach suitable for boundary-value problems analyzing nonlinear concrete behavior.

Muscle Constitutive Model With A Tangent Modulus Approximation: Ansys Implementation And Verification.

Journal of Biomechanical Engineering, 2023
Sophisticated muscle material models are required to perform detailed finite element simulations of soft tissue; however, state-of-the-art muscle models are not among the built-in materials in popular commercial finite element software packages ...

Bi-modulus materials consistent with a stored energy function: Theory and numerical implementation

, 2020
Many materials present different behavior in tension and compression. Within the infinitesimal isotropic theory, the widely used approach based on the Ambartsumyan theory presents only three independent constants to preserve symmetry of the elasticity ...

TensorHyper-VQC: a tensor-train-guided hypernetwork for robust and scalable variational quantum computing

npj Quantum Information
Variational Quantum Computing (VQC) faces fundamental scalability barriers, primarily due to the presence of barren plateaus and its sensitivity to quantum noise.

Anisotropy in elastic modulus of fault materials: Insights from the discrete element method

AIP Advances
The potential for earthquakes triggered by modulus softening in fault cores has been extensively documented, with a particular emphasis on calculating and characterizing the modulus within fault gouges. Traditionally, the modulus is treated as an average
