PFA Static
 

Progressive Failure Analysis Static (PFA_STATIC)

View Product Datasheet (PDF)

Product Highlights:

         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 levels.

         Optional use of conventional fracture mechanics approaches such as Virtual Crack Closure Technique (VCCT) and Discrete Cohesive Zone Model (DCZM).

         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.

Applications/Benefits:

         Aerospace, automotive and construction industries.

         Prediction/characterization of complicated failure mechanisms that can occur in aerospace and automotive composite structures.

         Prediction of damage and fracture initiation, progression and structural collapse.

         Determination of the ultimate strength of composite and metal structures.

         Determination of the residual strength of a composite structure after impact/fatigue.

         Prediction of inspection intervals and certification requirements.
