MSC/LS-DYNA Composite
Software and Database
DYNAMIC COMPOSITE SIMULATOR
Materials Sciences Corporation (MSC) and
Livermore Software Technology
Corporation (LSTC) announce the
Dynamic Composite Simulator module of
LS-DYNA. This enhancement to LS-DYNA
enables the most effective and accurate
dynamic progressive failure modeling of
composite structures currently available.
various fiber, matrix and interply
delamination failure modes.
Implementing this code will result in the
ability to optimize the design of
composite structures, with significantly
improved survivability under various
blast and ballistic threats.
MSC and LSTC have joined forces in
developing this powerful composite
dynamic analysis code. For the first
time, users will have the enhanced
ability to simulate explicit dynamic
engineering problems for composite
structures.
The integration of this module, known as
’MAT 161’, into LS-DYNA allows users to
account for progressive damage of
MSC’s LS-DYNA module can be used to characterize a
variety of composite structures in numerous
applications—such as this composite hull under blast
CAPABILITIES
• Database of elastic/strength properties
provides quick material selection of a wide
spectrum of composite materials including
Glass, Kevlar, and Carbon fiber reinforced
composite plastic materials
• Composite progressive failure models
integrated into LS-DYNA allow quickly
performing difficult dynamic impact
problems such as ballistic/blast impact,
crash and drop weight
• Composite micromechanical models can be
readily used to estimate elastic and strength
properties for selected composite systems
• Applicable to shell and 3D elements
• Upgraded output capability for damage zones
display
• Provides functionality of specifying initial
damage parameters for residual strength
evaluation
Wide Range of Impact Problems
• Low velocity impact
• Crush Analysis
• Penetration
Delamination
Fiber Tensile
Penetration involving perforation
behavior in composite armor
• Blast loading
• High speed ballistic impact
• Crash impact
ADVANTAGES
• Integrates best-in-class explicit dynamic
analysis code LS-DYNA with the MSC
composite progressive failure models

• Enables fast, accurate and effective
resolution of complicated dynamic
engineering problems for composite
structures
• Accounts for progressive damage of
various fiber, matrix and interply
delamination failure modes
• Includes material properties database for
both unidirectional and fabric composite

APPLICATIONS
This integrated software/database package
can be used effectively to design various
composite applications including:
• Lightweight impact resistant containers
and structures such as rocket motor cases,
pressure vessels, natural gas vehicle fuel
tanks, and other containment structures.
• Aerospace components such as wing
panels, launch vehicle components and
satellite components.
• Protection systems such as composite
armors of various levels of ballistic/blast
protection, helmets for aviation and
sports, blast barriers for buildings, blast
resistant containers, etc.
• Automobile parts for crashworthiness
capability such as car body, bumpers,
girders, steering wheel and steering
column.
Analysis results have been proven to correlate well to experimental tests
— such as this glass/VE composite target subjected to impact
