1 Introduction to LS-DYNA LS-DYNA is a program with capabilities to solve multi-physics problems such as solid mechanics, heat transfer, and fluid dynamics. Moreover, these problems could be solved either as separated phenomena or as couple physics. This handout is intended to assist the new LS-DYNA user get started. 2 Running LS-DYNA
LS-DYNA provides explicit and implicit solution schemes one code – one license – one data structure one input / output . Why implicit ? short . linear . low . high . explicit . implicit ?? explicit & implicit . long (static) Nonlinearity . Duration . How short is short duration? Before supercomputers (prior to 1980) short < 5 milliseconds.

WWW.LSDYNA-ONLINE Getting Started with LS-DYNA FSI Bulk modulus (modulus of compressibility) V V P B ' Chapter 11 - 4 The bulk elastic properties of a material determine how much it will compress under a given amount of external pressure. The ratio of the pressure to the fractional change in volume is called the bulk modulus of the material.
Tube expansion problem. This LS-DYNA simulation shows a simple Tube expansion example using the EM solver. A current is imposed in the coil which produces induced currents in the workpiece. This in turn generates Lorentz forces which cause the tube to expand. This problem is of medium size so running with 4 or more CPUs is recommended.
