Definition

Field	Contents	SI Unit Example
`Eltyp`	ELEM The variable is saved for all types of elements; except where not applicable. BEAM Beam elements SPRING Spring elements TRUS Truss elements
`Restype`	AMS Elements using AMS timestep due to /DT/CST_AMS DAM1, DAM2 or DAM3 Damage in direction 1, 2 or 3 DENS Density DT Element time step. 5 ENER Specific energy density (internal energy divided by the element mass). EPSD Strain rate for beam elements. EPSP Plastic strain $ε_{p}$ . For beam elements the mean plastic strain is calculated between all cross-section integration points of the beam. ESPN/N Plastic strain $ε_{p}$ output for integration point number N for /PROP/TYPE18 (INT_BEAM). ESPN/All Plastic strain $ε_{p}$ output for all integration points for /PROP/TYPE18 (INT_BEAM). EPSX Total strain XX (for TRUSS element only). HOURG Hourglass energy per mass unit P Pressure SIGX Stress XX SIGY Stress YY SIGZ Stress ZZ SIGXY Shear stress XY SIGYZ Shear stress YZ SIGZX Shear stress ZX TEMP Temperature THIC Thickness TILLOTSON Region identifier for Tillotson Equation of State (/EOS/TILLOTSON). USRi Variable of user law ( $i$ =1 to 18). VONM von Mises stress. MACH Mach number (/MAT/LAW151 (MULTIFLUID) only). OFF Element status Where, = -1 Element is not active (it is defined in an activated rigid body). = 0 Deleted element. Between 0 and 1 Under failure process. = 1 Active element. DAMG Mean damage value over integration points (only for /FAIL/GURSON). 6 EPSX Total strain XX (for TRUSS element only).

Comments

Damage in springs is defined as the maximum value between time 0 and the current time of the displacement versus failure displacement ratio: (1)
$DAM = {max}_{t} (\frac{δ (t)}{δ_{max}})$
For /PROP/TYPE13 (SPR_BEAM) springs, damage direction 1 is traction/compression, 2 and 3 are shear y and z.
For /PROP/TYPE8 (SPR_GENE) springs, damage directions 1, 2 and 3 are, respectively x, y and z.
The "SPH outputs" are available with /ANIM/Eltyp = ELEM/Restype (all Restype values; except Restype = THIC or HOURG). The Restype values: DAM1, DAM2 or DAM3 are only available with material LAW24 for brick element.
Element time step shows in animation only if elementary time step are computed for this element by Radioss. If nodal time step used (/DT/NODA) in computation , then no element time step shows in animation.
Option DAMG only used with /FAIL/GURSON to output damage value (ratio of total void volume fraction in current to it at ductile failure).(2)
$D = \frac{f_{t}}{f_{F}}$
