ELASTIC
Density ρ
- Control: value (
ValueField) - Unit: kg/m³
- Value modes: none (plain entry)
Matters twice in an explicit run: it is the inertia that carries the part into the floor, and with E it sets the speed of sound and so the time step.
Young's modulus E
- Control: value (
ValueField) - Unit: Pa
- Value modes: none (plain entry)
Poisson's ratio ν
- Control: value (
ValueField) - Value modes: none (plain entry)
PLASTIC
Yield stress σy
- Control: value (
ValueField) - Unit: Pa
- Value modes: none (plain entry)
Where the metal stops springing back. Required: an impact that stays elastic is not what explicit dynamics is for, and the dent you are after is the plastic strain past this point.
Hardening modulus B
- Control: value (
ValueField) - Unit: Pa
- Value modes: none (plain entry)
Flow stress = σy + B·εpⁿ. Zero is perfectly plastic. The library carries no hardening data, so this is yours to set and it survives a change of material.
Hardening exponent n
- Control: value (
ValueField) - Value modes: none (plain entry)
Between 0 and 1 for metals; 1 is linear hardening.
Problems reported against this step
The application reports no problems against this step.
… marks a value the application computes at run time, so the source carries no fixed text for it.
