Numerical modelling of dynamic response of underground openings under blasting based on field tests

This paper presents a numerical investigation of underground blasting tests using the LS-DYNA finite element code to assess the performance of ground support systems under dynamic loads. The study employs specific material models, such as the RHT model for rock and a JWL equation of state for the explosive, to simulate the dynamic response and crack patterns observed in field experiments. The finite element model was then used to analyze how different aspects of the blast design, including charg

Human Response to High-Rate Loading

Lance Frazer and Daniel P Nicolella

This study utilizes advanced parametric modeling and shape optimization techniques to develop a probabilistic finite element model of the tibia and talus. By integrating statistical shape analysis with robust mesh correspondence methods, the research captures anatomical variability and predicts fracture risk under high-rate loading conditions.

Application of An a priori Jacobian-based Error Estimation Metric

Robert Rainsberger, Jeffrey T. Fong, and P. Marcal

This paper introduces a new metric called the "Standard Error" for assessing the mesh quality of 3D Finite Element Method (FEM) simulations. This metric, based on the Jacobian matrix, allows for the comparison of mesh quality across different element types and models. The study demonstrates its application to various 3D finite elements and includes examples with and without analytical solutions.
