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.

carried out with the implicit solver of LS-DYNA and the full integration shell formulation 16 In this study, AA5754 tubes were hydroformed using 64 mm of end feed at each tube end The crush models incorporated a rigid wall moving in the axial direction of the tube at an initial velocity of 7 m/s with a mass of 560 kg, crushing its free end...
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.

Edit the job name to your choice – again in this example we will use LS-DYNA Restart Tutorial [Step 2]. Replace the original job command from part 1 with the following ls-dyna -r d3dump01. The inclusion of the -r d3dump01 flag allows the LS-DYNA to initiate a simple restart and will begin the simulation from the point at which the job was ...

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.
