LIMIT_2016.pdf

Introduction


Novelties 2016Improved DVS1612 implementation

New formulation for the static weld factor in multiaxial loadingin FKM and DVS1612

Improved report generator with better stability

New interface to Solidworks version 2015

User programmed python modules can be used to customize GUI

Weld Sets at Shell-Solid-Interface

Splitting of welds for local redefinition

Improved stress description in LIMIT-Viewer

Simpler definition of FE-Result in LoadManager by file

New license server

New interfaces: ABAQUS2016 and Ansys V161/V162/V170

Overview


Enhanced DVS1612Fatigue and static strength data defined in EditSetup

Static weld factors are user defined or according to FKM

Different equivalent stress types for weld section available

Enhanced DVS1612 Assessment


Enhanced DVS1612Material selection according to EN10025

Yield and tensile strength depending on sheet thickness



Enhanced DVS1612Assessment defined in JobManager

DVS1612_FATIGUE (Default pure DVS) Is formulated in upper or maximum stress

Uses original interaction formula for multiaxial loading

DVS1612_FATIGUE_AMPLITUDE Is formulated in amplitudes rather than upper or maximum stress

Uses modified interaction formula for better interpretation

DVS1612_STATIC Performs a static analysis with data defined in EditSetup



Modified weld factors in FKM and DVS1612New formulation calculates an effective weld factor depending in thetype of effective stress formulation and on the different weld factorsdepending stress type and sign and weld parameters.

Empirical effective weld stress according FKM: V = SQRT[S_2^2+T^2]

Empirical effective weld stress weighted by weld factors awV_aw= SQRT[(S_2/aw)^2+(T/awt)^2]

Effektive weld factor:aw_eff = V_aw/V

Static Weld Assessment


New Interface to SolidWorksModel information and results can be selected and exported for the strength assessments in LIMIT

Currently SWX version 2015 is supported. If other versions are needed, please contact LIMIT support for further information.

SolidWorks


User Programmed Python ModulesUser defined modules are located in the directory….\LIMIT-CAE-RELEASE-2016\user_imports

Source of Report Generator is included in this version and can be modified by users. For further information contact the LIMIT support!

Splitting of WeldsType of weld can be changed locally

For an existing setup (e.g. PS0001) two new sub-setups are derived:

PS0001-origin … with original definitions

PS0001-redefine … with modified data

Saves time and increases the accuracy

Splitting of Welds

Different weld type


Splitting of WeldsMark Setup in SetupManager

Select regions to separate in the viewport

Select the Split option in the SetupManager(RMB)

Define name and editing mode

Splitting of Welds


Import of FE-Result definitions via text fileOne line per FE Result: Name, Step#, Increment#, Path\Filename

E.g.: torsion, 1,,D:\work\workshop_1-3_non-welded_shaft\shaft.op2

Define FE Results by File


Improved stress description in LIMIT-ViewerStress output is activated in the JobManager/Edit

Stresses shown in Viewer have better description

Define FE Results by File


New license server Server is installed asa real service
