Accurate modeling of a truck tire for predicting dynamic characteristics requires an adequate representa- tion of its composite plies. This study compares two approaches in modeling the multi-layered structure of a rolling radial-ply ...

Porous metals have been increasingly used in modern engineering applications over the past decades due to their multi-functionality and attractive combination of mechanical and thermal properties [1]. The understanding of their ...

The LS-TaSC Version 3.1 topology and shape design tool is presented. The presentation introduces the multi-point numerical derivatives scheme that allows constrained optimization using the mass fractions and load case weights as ...

Accurate modeling of a truck tire for predicting its dynamic characteristics requires an adequate representation of its composite plies. This study compares two approaches in modeling the multi-layered structure of a rolling ...

Simulating the masticatory system during chewing, clenching and bruxism, requires a model that captures the dynamical behavior of its different components: the mandibula and maxilla, the temporomandibular joint (TMJ), the teeth, the ...

LS-DYNA offers a wide variation of material cards to cover different needs in diverse applications. However, choosing the most proper material model among 250 keywords can be quite deceptive. Therefore, an algorithm has been developed ...

LSTC is continually improving the capabilities and performance of Implicit especially in the distributed memory computing environment. This talk will review recent improvements such as (a) removing serial memory restrictions with a ...

In deep-drawing dies for steel sheet parts of car bodies huge masses are moved. To prevent vibrations, which occur by sudden acceleration or breaking of those masses, elastomeric tubular dampers are used. The dampers are made out of ...

This talk gives a brief review of the recent updates in frequency domain solvers in LS-DYNA. A series of frequency domain solvers have been implemented to LS-DYNA since ls971 R6. They include FRF (Frequency Response Functions), SSD ...

Model Reduction Techniques (MRT) are algebraic approximation solutions allowing for fast (real- time) interpolations (reconstruction) or extrapolations (prediction), based on previously existing DOE-type results, obtained either from ...
