INTRODUCTION:

MatDB is a windows platform program to handle a metallic material database with more than +4700 materials frequently used in engineering.Metallic Material Database with +4700 refs

  • Fast: Material properties are obtained immediately from search filters used as input
  • Easy: User-friendly interface to search materials in database
  • Formatted output: Report with mechanical properties obtained is ready to be used in documentation

INPUTS:

When selecting a new database in MatDB, a list with all materials in the database appears:

matdb2

 

It is possible to manually navigate through the list in order to find the desired material. Once a material of the list is selected, its properties are displayed in the property tables. In order to ease the search, it is possible to introduce some keywords in the textbox at the top of the window to narrow the list. If more than one keyword is introduced (separated by spaces), the search algorithm looks for those materials satisfying all the criteria simultaneously

OUTPUTS:

  • Stress-strain curve: MatDB computes the stress-strain curve of the material following Ramberg-Osgood formulation. Engineering stress-strain curve, true stress-strain curve and stress – logarithmic plastic strain curve can be obtained. Points of the curves can be written in a plain text “.mat” file to be used in an external application

matdb3

  • Output Report: It is possible to print out a report of any material object created in the session, to be appended to other documents or simply to manage the data more easily. The report is a self-containing “.docx” file that summarizes the material information, includying an image of the currently printed stress-strain curve.

1. INTRODUCTION:

FrameLoad is a post-processing program to obtain loads on frame sections.

Im_1_2

In each section there is influence of several elements. Load extraction of a section is based on summation of forces in a specified point according to a coordinate system previously defined by the user. Origin of coordinate system is the same as the load summation point.

2. INPUT FILES:

Three main input files are needed by the program:

  • Nastran results file – f06
  • Topology model file – “cabecera”
  • Section definition file – input.dat

3. OUTPUT FILES:

Two kind of output files are obtained from FrameLoad software:

  • *.ren file (for each one f06 file). This file contains the Axial, Shear & Moment loads for all load cases in f06 file and sections.
  • *.env file. This file contains the Axial, Shear & Moment load envelopes for all sections.

Ten critical load cases are selected by frame sizing from the complete set of load cases, according to the following criteria:

  • Axial load (maximum and minimum)
  • Shear load (maximum and minimum)
  • Bending moment (maximum and minimum)
  • Stress in free flange (maximum and minimum)
  • R stress (combination of axial and shear stress)
  • S load (combination of axial and shear stress)

INTRODUCTION:

boltBOLT GROUP 3D is a software tool to calculate shear and tensile forces for each fastener in riveted or bolted joints. The method is valid only for components that are sufficiently stiff in the joint area. For the static strength analyses the centroid of the fastener group is determined taking into account the allowable forces of the fasteners

  • FastLoad per bolt is obtained immediately 
  • Graphical Formatted Representation: Graphics with bolt load distribution obtained as result are ready to include in documentation
  • Validation: A load check is done as validation of input/output data

INPUTS:

Input data required for the analysis is:

  • Properties of Riveting: This information has to be filled for each type of rivet (or fastener) that appears in the Bolt Group distribution.
    1. Name of the rivet: internal name use in the Excel Sheet.
    2. Allowables: shear, tension rivet and tension nut allowables.
  • Position, type and effectiveness: complete one row for each rivet or fastener (50 rivets maximum):
    1. Rivet number: from 1 to the number of rivets.
    2. Rivet Type: same name as appears in 1.
    3. Coordinates: position of the rivet. The excel sheet supports only rivets that are located in the xy plane with z-coordinate = 0.0 and the z-axis as tension axis.
    4. Effectiveness (Yes/No): user has to consider if the rivet admits shear and tension.
  • Applied Loads:
    1. Application Point: position where the load is defined
    2. Load: force and moment components.

OUTPUTS:

When the parameters are filled, BOLT GROUP 3D tool automatically calculates loads per rivet, and graphical distribution of bolts and loads is shown when pressing button “Refresh Graphs”. A simple check can be done comparing Load Check cells with the Input Load to know if the results fulfil balance of forces and moments.
