COSMOSWorks Finite Element Analysis & Services

Assumption of static & linear load

Static load: All loads are applied slowly and in increments until they have reached their full capacity and force. After reaching their full capacity these loads remain constant. This assumption allows us to neglect forces resulting due to inertia due to the minimal acceleration and forces.

linear load: the relation of loads and the induced reaction their of is linear. If for example a load or force is doubled, the behavior and reaction of the model (displacement, elongation and tension) are also doubled. The case of a linear load can be assumed under the following conditions:

• All materials behave according the law of Hooke, in which the tension stands in direct relation to the elongation,
• The induced displacement are so minor that the stiffness is not influenced by the loads induced,
• The constraints and influencing factors do not change during the application of a load. The loads must remain constant regarding direction, force and applied surface.

The Finite Element Analysis tool COSMOSWorks is completely integrated into the CAD software SolidWorks. This tool is available in different versions. Integrated into the Office suite of SolidWorks is the simple solver COSMOSXpress. This solver offers the possibility to test the structural integrity of parts and models given a specific load.

We work with the tool COSMOSWorks Designer.

COSMOSWorks designer is Software solution in with which buckling, frequency, tension, thermodynamic and optimizing analysis can be calculated and created.

FEA Mesh

The Finite-Element-Analysis (FEA) offers a reliable numerical method for the analysis of constructed parts and models. The first step for this analysis, apart from creating the model itself is the meshing of the part. The software creates an automatic mesh of the model by creating small and simple geometric forms, the elements, which in turn are connected at nodes. This network of elements and nodes are the basis for the calculation.

Irregular pressure and forces

COSMOSWorks has the capability to calculate and simulate a uneven pressure, as applied for example on a tank or reservoir. Alternatively this feature can also be used for a uneven force placement on a part or model.

rule of thumb: FEM/FEA tools should be used as an additional validation of construction processes. The results gained in such a tool should only be regarded as complementary to experience and practical tests conducted.

with COSMOSWorks the number of practical tests can be reduced i.e. cost and time to market can be rationalized and efficiency increased.
