Dynamic Implicit analysis with cohesive elements

Dynamic Implicit analysis with cohesive elements

Dynamic Implicit analysis with cohesive elements

(OP)
It's possible to do a dynamic analysis of a composite laminated with delamination, using cohesive elements?

My objective is to analyze the frequency response function (FRF) and the natural frequencies of the laminated.

RE: Dynamic Implicit analysis with cohesive elements

Yes, but no. FRF and natural frequencies apply to linear systems, so there's no particular advantage in using cohesive elements. You could do some sort of staged approach, ie do a linear analysis at distinct stages as the structure deforms, I suppose. As to the rest of your question, yes. Google.

Cheers

White Paper - Reshoring Prototyping and Production
In this whitepaper, we'll provide insight into why and when it makes sense for U.S. manufacturers to reshore prototyping and production, and how companies can leverage the benefits of working with local design, prototype, and manufacturing partners during the pandemic and beyond. Download Now
Engineering Report - Top 10 Defect Types in Production
This 22-page report from Instrumental identifies the most common production defect types discovered in 2020, showcases trends from 2019 to 2020, and provides insights on how to prevent potential downtime in 2021. Unlike other methods, Instrumental drives correlations between a variety of data sources to help engineers find and fix root causes. Download Now
White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
