Multi-Scale Modeling of Composites A paradigm shift in the optimal engineering
of composites materials & structures

Interview
Roger Assaker is the CEO of e-Xstream engineering, he will present the latest advancements in behavior simulation during the
Boston JEC ICS conferences.

JCM: How can behavioral simulation
change the composite industry as we
know it?

Roger Assaker : These days, the

engineering composite structures follows the "building block approach"
that is dominated by extensive testing
to determine the material and design
allowables. The composite is treated as a
"black metal" and compared to the tested
allowables augmented by a substantial
safety factor. All this results in a long and
costly design and engineering process
and sub-optimal composite structures.
Advanced simulation methods, focusing
on the actual behavior of the composite,

can help reduce the time and cost of
engineering optimal composite structures while increasing the confidence and
reducing the safety factors.
JCM: What is the expertise of
e-Xstream in this field?

R. A. : e-Xstream is a unique software

and engineering company 100% focused
on advanced composite modeling. We
help our customers reduce the time
and cost needed to develop and use
composite materials. We offer Digimat,
the material modeling platform combining the tools, solution and expertise
needed to enable composite materials
and structures engineering. Digimat
uses nonlinear multi-scale modeling
technology to predict the behavior of a
composite based on the behavior of its
constituents (matrix/fibers) and on the
underlying microstructure (fiber content,
length, orientation) as dictated by the
manufacturing process. We model a kind
of composites (i.e. Multi-phase materials) ranging from engineering plastics

(e.g. short fiber reinforced thermoplastics used in the Auto or E&E industry)
to high performance CFRP (e.g. UD
Tape of Woven Carbon fiber reinforced
Thermosets).
JCM: What are your main goals during this
speech in Boston in October?

R. A. : Our main objective from our

presentation in Boston is to share with
the industry our vision regarding composite modeling. In other terms, how effective and efficient composite modeling
can help the industry reduce the time
and cost of designing optimal composite
structures.

place on October 29th in Boston during
the JEC Composite conferences.
