  • Accurately measuring ultraslow motion
    and permanent deformation called creep. Creep tests are conducted at a constant high temperature and load that ultimately determine a material's creep rate. They are especially common in aircraft applications. It lets engineers, for example, determine how much a turbine blade in the hot section...
  • Melt Flow Rheology Testing for Polyolefins
    by using an Arrhenius fit of zero shear viscosity ? 0 verses temperature. Nornally used with the Ellis Flow Model and TTS modeling of master curves of polyolefins. Zero shear viscosity - ?0 can be used for several models, calculations, and with dynamic, stress relaxation, creep compliance, and relaxation...
  • MICRO: Products
    . The tension/compression load cell offers low creep and delivers accuracy to 0.02% in loads ranging from 250 to 100,000 lb. The standard output is 4 mV/V for ranges >5000 lb, with an excitation of 10 V dc. The unit has amplifier options. MICRO: Products...
  • Metrically measured motions
    an upper-axis moving mass of 8.6 kg. The leadscrew has a lead of 5 mm (0.005 m) and a diameter of 18 mm (0.018 m). The manufacturer gives this particular leadscrew an efficiency value of 0.6 when using antibacklash nuts. The table moves a 23-kg payload. This load must accelerate at a rate of 2 m/sec2...
  • Mounting Sensor Magnets with Tolerance Rings
    the many design constraints providing a spring rate strong enough to hold over a large tolerance range yet soft enough to prevent damage to the magnet material. The typical material used in Tolerance Rings is 301 stainless steel, which is slightly magnetic due to in process work hardening, which...

About Chris Mason. Chris graduated from Portsmouth Polytechnic in 1983. His interest in software began...
  • Predicting plastic part life
    polymers combine viscous and elastic response (viscoelastic), so the measured phase angle falls between 0 and 90°. The phase angle and the stress and strain amplitudes measure a material's elastic and viscous response or storage and loss modulus. It also reveals damping efficiency (tan ), creep and stress...

  • MICRO: Enabling advanced lithography through active vibration control
    equipment through the floor can be isolated effectively. In addition, in certain cases onboard disturbances such as fans or moving stages can be isolated from the rest of the tool using polymeric materials. However, material sag and creep can lead to deviations in the equipment's static alignment...
