Progressive Failure Analysis Static (PFA_STATIC)
Predicts the maximum loads that composite and metallic elements
and structures can sustain using a step-by-step virtual loading procedure that
takes into consideration material degradation, nonlinearity and changes in
structural geometry. Degradation of material properties is based on 1) matrix
plasticity and micro-cracking; 2) fiber orientation changes and breakage; and
3) environmental effects and manufacturing defects.
Predicts crack initiation and growth. The program computes
various damage locations and failure modes in composites caused by the
application of external static loads, temperatures and environmental effects.
Predicts damage events at different material scales beginning
with the micro-cracking in fiber, matrix and fiber/matrix interface. Damage
propagation is tracked from the micro-level to ply, laminate and structural
Optional use of conventional fracture mechanics approaches such
as Virtual Crack Closure Technique (VCCT) and Discrete Cohesive Zone Model
Predicts the post-buckling response of a composite structure
based on the superposition of a required scaled buckle shape on the initial
geometry of the structure.
Predicts the time to failure as well as time-dependent crack
initiation and growth in composite elements and structures caused by external
static loads, temperature and environmental effects (creep response).
Effective for permeability and damage tolerant design of
composite structures. The program computes crack density and corresponding
material degradation in composite materials during the loading process.
Can be used as a virtual testing tool to reduce physical
experimental testing by closely simulating the actual testing process.
Comes with its own default finite element solver MHOST.
Integrates numerous commercial FEM software's including:
MSC.NASTRAN, MSC.MARC, ABAQUS, ANSYS and LS-DYNA. Allows the user to import,
handle and run finite element models prepared for MSC.NASTRAN, MSC.MARC,
ABAQUS, ANSYS and LS-DYNA.
