All these technologies use a liquid material, namely a thermoset polymer. The liquid resin is held in a vat onto which a laser or light source is flashed. This laser or light cures (hardens) the material to make
Usually, axial forces, not twisting moments, carry loads in trusses. Trusses are lightweight and force-efficient. The strength and stiffness of truss components determine their load-bearing capacity. The structural analysis considers loads, support conditions, and material qualities while designing ...
Oil whirl is related to the bearing oil stiffness which has an eccentric resonance frequency that follows the rotational speed. Oil whip is related to the shaft stiffness which has an eccentric structural resonance frequency not following the rotational speed. Due to the oil flow velocity, whirl...
What is topology optimization? Topology optimization is a mathematical method used in engineering to design structures that maximize performance while minimizing material usage. It involves finding the best shape and layout for a structure to achieve desired goals, such as strength, stiffness, or weight...
What does COM stand for in biomechanics? What is applied biomechanics? What is ROM in biomechanics? What is an extensometer in biomechanics? What is MVIC in biomechanics? What is human biomechanics? What is computational biomechanics? What is stiffness in biomechanics?
钢管填充混凝土能提高截面的刚度,这个是大家都知道的,也是实际项目中遇到刚度不够时候常常采用的招,那到底从钢管截面变为钢管混凝土截面,刚度能提高多少?似乎平时都没有具体算过。以下就搞个简单截面,定量算算。(What is the difference in stiffness between steel tube and concrete-filled steel tube section?) ...
If e.g. the test structure is fixated at some positions under test, that is going to vibrate freely when the test structure is operating in real life, then the measured dynamic properties will not fully relate to the real-life usage of the structure - since adding stiffness to the structur...

A linear analysis predicts the behavior of a material like a metal spring which retains a constant stiffness when subjected to a force (until it hits a predictable failure point.) In other words, the outcome is always the same and well-understood. Most CAD packages include linear FEA. 99%...
