solves nonlinear impact problems that involve large deformations with complex
contact and motion. Typical applications include crash, metal forming
processes, drop tests and ballistic scenarios. NEi Explicit can also be used to
solve static problems with millions of degrees of freedom. Because they are
extremely large and highly contact dominated, these problems are difficult to
solve using implicit FEA codes. It is completely
integrated with the NEi Nastran environment, making the learning process much
easier for Nastran users who are transitioning to an explicit solver. Existing
Nastran users can directly analyze a Nastran implicit model in the NEi Explicit
solver without any changes to the analysis file. The explicit architecture
lends itself to highly scalable parallel performance, and large deformation
contact solutions with highly nonlinear material behavior. NEi Explicit
provides analysts with automatic contact generation, rigid materials
definition, material deletion criteria with element deletion, and automatic
reconstruction of contact surface due to surface erosion.
Artificially created metamaterials are already appearing in niche applications like electronics, communications, and defense, says a new report from Lux Research. How quickly they become mainstream depends on cost-effective manufacturing methods, which will include additive manufacturing.
Sharon Glotzer and David Pine are hoping to create the first liquid hard drive with liquid nanoparticles that can store 1TB per teaspoon. They aren't the first to find potential data stores, as Harvard researchers have stored 700 TB inside a gram of DNA.
