SPECIFIC HEAT

18.27

SPECIFIC HEAT: Deﬁne speciﬁc heat.

This option is used to specify a material’s speciﬁc heat.

Products: ABAQUS/Standard ABAQUS/Explicit

Type: Model data

Level: Model

Reference:

•

“Speciﬁc heat,” Section 20.2.3 of the ABAQUS Analysis User’s Manual

Optional parameter:

DEPENDENCIES

Set this param eter equal to the number of ﬁeld variables included in the deﬁnition of speciﬁc

heat. If this parameter is om itted, it is assum ed that the speciﬁc heat is constant or depends

only on temperature. See “Specifying ﬁeld variable dependence” in “Material data deﬁnition,”

Section 16.1.2 of the A BAQU S Analysis User’s Manual, for more information.

Data lines to specify a material’s speciﬁc heat:

First line:

1. Speciﬁc heat per unit mass. (Units of JM

−1 −1

2. Temperature.

3. First ﬁeld variable.

4. Second ﬁeld variable.

5. Etc., up to six ﬁeld variables.

Subsequent lines (only needed if the D EPENDENCIES parameter has a value greater than six):

1. Seventh ﬁeld variable.

2. Etc., up to eight ﬁeld variables per line.

Repeat this set of data lines as often as neces sary to deﬁne the speciﬁc heat as a function of temperature

and other predeﬁned ﬁeld variables.
