Modeling Microvoid Localization with Explicit Finite Element Analysis
… has typically been performed with an implicit finite element analysis (FEA) solver, which accurately produces quasi-static results, but introduces limitations in terms of computational expense and the ability to model highly non-linear processes. This has resulted in the majority of studies …

Numerical investigation of dispersion in Hopkinson Pressure Bar
… for strain rates between 102 S-I and 104 S-I. Explicit Finite Element Analysis (FEA) codes are increasingly used to model HPB experiments numerically, due to the complicated boundary conditions imposed by tensile and shear SHPB experiments. However, most publications on numerical modelling of …

Development of a Progressive Failure Model for Notched Woven Composite Laminates
… propagation was developed and implemented in explicit finite element analysis to simulate woven composite materials. Several failure criteria and propagation models were investigated and compared. A response surface was used to better understand the effects of damage parameters on the failure …

Dynamic Shear Bands in Metals under High Strain Rates
… under different conditions in many applications. Analysis of these localizations highly depends on the selection of the constitutive model. Hence, two constitutive models that take temperature and strain rate effect into account are proposed. The first model is a physically based model that …

Surrogate-based global optimization of composite material parts under dynamic loading
… an optimization approach based on design and analysis of computer experiments (DACE) in which smart sampling and continuous metamodel enhancement drive the design process towards a global optimum. Kriging metamodel is used in the optimization algorithm. This metamodel enables the definition of …

Behavior and performance of steel moment-framed buildings subject to dynamic column loss scenarios
… of this event prevents simple design-based analysis approaches from providing accurate assessments of collapse resistance. This research employed a set of two prototype steel moment-framed buildings to study dynamic ground-level column-loss scenarios for a variety of column locations within …

The Effect of a Low-Velocity Impact on the Flexural Strength and Dynamic Response of Composite Sandwiches with Damage Arrestment Devices
… In this study, the experimental and numerical analysis of composite sandwiches were investigated, which included static 4-point bend and vibration testing. Composite sandwiches were constructed utilizing four-plies of Advanced Composites Group LTM45EL/CF1803 bi-directional woven carbon fiber …
