NextFEM Designer allows to use custom material and section libraries, adapting to the needs of an international audience.

Expand material library

The material library can be expanded by writing a CSV file (i.e. a text file using the semicolon separator), as in the following examples.

  • Steel

Name;Code;E [MPa];G [MPa];nu;fyk [MPa];ftk [MPa];Wd [kN/m^3];Md [kg/m^3]

S235;UNI EN 10025-2;210000;80769;0.3;235;360;78.6;801.2232416

S275;UNI EN 10025-2;210000;80769;0.3;275;430;78.6;801.2232416

  • Concrete

Name;Code;E [MPa];G [MPa];nu;fck [MPa];Wd [kN/m^3];Md [kg/m^3]

C8/10;NTC2008;25331;10555;0.2;8;25;254.841998

C12/15;NTC2008;27085;11285;0.2;12;25;254.841998

For other types of materials, all the columns are mandatory except for “fck”, “fyk” and “fck”.The extension of the file have to be *.nfm.

WARNING: units have to be written between square brackets

Expand section Library

The section library can be expanded by writing a CSV file (i.e. a text file using the semicolon separator) as follows:

Name;Code;h [mm];b [mm];tw [mm];tf [mm];r [mm];A [cm^2];Jy [cm4];Wey [cm^3];Wpy [cm^3];iy [cm];Avz [cm^2];Jz [cm^4];Wez [cm^3];Wpz [cm^3];iz [cm]

IPE A 80;UNI;78;46;3.3;4.2;5;6.375401837;64.37774091;16.50711305;18.97743881;3.177708713;3.070001837;6.852668856;2.979421242;4.692462888;1.036754887

The first four columns are mandatory. The extension of the file have to be *.nfs..
