Design Considerations during Design of Rubber Parts

During designing a rubber component, multiple factors need to be taken care of. These factors are as listed: material considerations with required technical specifications and also as per applicability and function, radius and wall thickness, gate location in mould, rib inclusion, mould shrinkage and draft. Basic Design Aspects (Wall Thickness, Radius, Draft) While designing rubber components, some basic aspects to adhere to is wall thickness. Most of industry hoses or pipes are made of rubber...

How to Create Embossing and Engraving in CATIA V5 and CATIA 3DEXPERIENCE

Embossing is a metal forming process for producing raised or sunken designs or relief in sheet metal by means of matched male and female roller dies, theoretically with no change in metal thickness, or by-passing sheet or a strip of metal between rolls of the desired pattern. Steps to create embossing/engraving in CATIA V5: In the first step, open a blank drawing file from CATIA drafting workbench. In this drafting file, one has to insert the text that needs to be engraved or embossed. Any font...

Links Management in CATIA V5

CATIA link is a dependency relation used to share geometric, parametric or positioning information between components in CATIA V5. Links in CATIA are unidirectional and always point from the child to the parent. Types of Links There are five types of links each of which are explained below with a common example. The CCP link The first CAT Part contains the geometrical definition of the raw material used to create the table leg. The second CAT Part contains the geometrical definition of the finished...

Understanding Boolean Operations in CATIA V5

Boolean operation is an important feature in CATIA V5. Types of Boolean operations include Assemble, Add, Remove, Intersect, Union Trim, and Remove Lump. Assemble The Assemble command basically works considering the polarity of the solid bodies. One may be interested to know what actually is the polarity of a body. In simple words, it can be said that whenever a new body is created using material formation like pad, shaft and rib or multi-section solid, then that body can be considered as positive...

Design Considerations during Design of Plastic Parts

Plastic part design consideration plays a significant role in designing and manufacturing a plastic component. Whenever a Product Designer designs a plastic part, it is important to take care of factors such as the moulding process, selection of material, mass manufacturing process and overall area of the part around the functional need by keeping the design intent intact or the end use in consideration. Overall Area of the Part While engineering plastics are used in many diverse and demanding...

Understanding Abaqus Standard Negative Eigenvalue Messages

Negative eigenvalue messages are generated during the solution process when the system matrix is being decomposed. The messages can be issued for a variety of reasons, some associated with the physics of the model and others associated with numerical issues. An example of the message that is issued is: ***WARNING: THE SYSTEM MATRIX HAS 16 NEGATIVE EIGENVALUES. IN AN EIGENVALUE EXTRACTION STEP THE NUMBER OF NEGATIVE EIGENVALUES IS THIS MAY BE USED TO CHECK THAT EIGENVALUES HAVE NOT BEEN MISSED. NOTE:...

Troubleshooting Abaqus/Explicit analyses that use contact pairs

This blog explains the different errors encountered while using Abaqus/Explicit and the ways to debug and troubleshoot them. Tracking Difficulties Reason: By default, Abaqus/Explicit uses a fast, local tracking algorithm to track the penetration of a slave node into the master surface; at a frequency of every 100 increments (the user can change this default), Abaqus/Explicit performs a global search. If penetration by a slave node goes undetected for a period of time (in between the global...

Common Errors and Warnings in Contact and Convergence

While running the analysis on a model with contacts, a major problem arises i.e. convergence. It is not just because of single reason, that it can be resolved in an easy way.  When you come across such problems in different types of analysis, job will terminate by showing an error message or a set of warnings in the analysis. That means the solution is unable to converge. There are different reasons for why an ABAQUS analysis fails in obtaining the convergence.  The main key area we need to look...

Performance settings in CATIA V5

There are many ways to manage the performance of CATIA V5 & accuracy of models. To improve performance & increase productivity, we need to configure the settings properly. Some of these options are discussed in detail in this document. These will immensely benefit CATIA users. Undo Stack Undo ➞ Stack size ➞ change from 10 to 5 Stack Size defines the maximum number of commands which can be undone for each document. Lower the value better the performance. More the stack value,...

Using Publications in CATIA V5

With the help of Publications in CATIA V5, one can make different geometrical features available for use in the specification tree. One can publish a plane, a sketch or a parameter which is not readily visible in the specification tree. In assembly workbench, during Contextual Design, Publication option becomes very useful. In CATIA V5, go to Tools ↦ Publication The Publication command is used to: Publish a geometrical element Edit the default name of the published element ...
