chapters
micromechanics

cadec-online.com implements micromechanics composites reinforced unidirectional fibers, , random fibers, plain weave, twill, , satin textiles. predicts lamina elastic moduli, strength values, coefficient of thermal expansion (cte), moisture expansion, , other micromechanical properties. application conducts analysis through several theoretical models, including:



cylindrical assemblage
halpin-tsai
periodic microstructure model (pmm)
rule of mixtures (rom, woldemar voigt (1887)) , inverse rom (a. reuss (1929))
stress partitioning

lamina analysis

cadec-online.com can calculate three-dimensional (3d) stiffness , compliance matrices, two-dimensional (2d) reduced stiffness , compliance matrices, in lamina coordinate system (cs). capable of transforming composite laminates matrices other coordinate system. lamina types supported software include:



unidirectional. lamina properties calculated using micromechanics.
random, continuous/chopped strand mat. lamina properties calculated using micromechanics.
fabric/textile. lamina properties calculated using micromechanics.
experimental. lamina properties given user, based on testing or material supplier data.

laminate analysis

the application can carry out laminate analyses including calculation of laminate stiffness, stress, strain, , failure. software supports intact , damaged laminates (see damage mechanics). each category, cadec-online.com can calculate laminate thermal stresses, laminate coefficient of thermal expansion, laminate stiffness , compliance matrices composite laminates. also, application can predict laminate moduli, orthotropic material equivalents stiffness of laminate in both bending , membrane modes of deformation.


failure analysis

cadec-online.com predicts failures such first ply failure (fpf) , last ply failure (lpf) under mechanical, thermal, , moisture loads, in situ effects, using several failure criteria (fc) including:



maximum strain
maximum stress
interacting fc
hashin fc
puck fc
truncated maximum strain

damage mechanics

uses discrete damage mechanics (ddm) predict crack density vs. strain symmetric laminate subjected membrane state of strain. results can exported excel plotting. state variable describing damage state of material crack density in each ply. thermodynamic force midsurface strain applied laminate. relevant material properties fracture toughnesses in modes (opening) , ii (shear) of ply.


textile reinforced composite analysis

the application can predict stiffness , strength of composite materials reinforced plain weave, twill, , satin textile, called fabric. textile lamina idealized transversely isotropic material. calculated textile lamina can used other lamina in rest of application. calculated properties include:



five elastic moduli
seven strength values
two coefficients of thermal expansion (cte)
two coefficients of moisture expansion (cme, see hygroscopy)

thin walled beam analysis

the application able analyze laminated composite thin walled beams general cross sections. beams can asymmetric , loaded general combinations of forces in 3 planes (axial, vertical , horizontal) 3 moments (torque , 2 bending moments). cadec-online.com computes section properties such shear center.

the main screen of flipnote creation interface. largely similar predecessor, flipnote studio 3d allows users create short animated sketches known flipnotes. flipnotes can made of hundreds of frames, , can played @ variety of speeds. software offers users option create 3d flipnotes drawing different parts of animation on 3 layers. the main tools include pen, eraser, , paintbrush. new flipnotes studio 3d tools draw shapes, fill enclosed areas (paint bucket), , insert text. application features limited color palette, including black, white, red, blue, green, , yellow. slight improvement upon flipnote studio, didn t include yellow , green selectable colors, still possible using color mixing. selection tool used copy , manipulate parts of frame. users can use 3ds system s camera , microphone add audio , photos creations. these animations can either shared on application s native online community, or exporting them gif or avi files.
