  • FE Update: Simulating Plastics in Drop and Crash Tests
    elastic behavior but show no plasticity. Metals, on the other hand, show a highly linear elastic behavior, with plasticity becoming relevant only after yielding. But the stress-strain behavior of plastics is neither hyperelastic nor linear. Contrary to metals, plastic strain begins prior to yield...
  • Get Reliable Results From Rubber Test Data
    , and R = volume change with temperature. The elastic volume ratio, J, and the invariant functions, I1 and I2, are related to the extension coefficients λi = 1 – εi where ε1, ε2, and ε3 = the principal strains: I1 = λ1 2 + λ2 2 + λ3 2. I2 = (λ1λ2)2 + (λ2λ3)2 + (λ1λ3)2. J = λ1λ2λ3. Strain-energy...
  • Making the strain
    rejection is possible by applying strain gages to the specimen itself. A static calibration within the elastic limits of the material effectively converts the test specimen into a miniature high-stiffness load cell that is unaffected by the resonance of other system components. The technique is most...

The residual stress measurements were. corrected for both the penetration of the radiation. into the subsurface stress gradient [12] and for. stress relaxation caused by layer removal.[13]. The value of the x-ray elastic constants required. Figure 2. HCF (4-point...
  • Boeing Uses LMS SYSNOISE to Predict Acoustics of Aircraft Cabins
    and elastic medium. This makes it possible to connect the structural model to an acoustic model. Boeing uses LMS SYSNOISE for acoustic modeling because it simplifies the process of coupling to a structural model. One advantage is that LMS SYSNOISE provides a robust coupling method that does not require...
  • Vibration Isolators Protect Electronics at Low Frequencies
    efficiency means a bench top negative-stiffness unit is sufficient to isolate a piece of equipment from environmental vibrations. Simplicity can mean less maintenance and longer life, too. Negative- stiffness isolators are designed for repeated elastic deformation. The components do not deform...
