  2. Dynamic load testing - Wikipedia

    en.wikipedia.org/wiki/Dynamic_load_testing

    Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber ...

  3. High strain dynamic testing - Wikipedia

    en.wikipedia.org/wiki/High_strain_dynamic_testing

    The dynamic component is computed as the product of the pile velocity times the damping factor (a soil parameter related to soil grain size). The static component is the total soil resistance minus the dynamic component). Dynamic load testing takes a further step in analyzing the data and computing static capacity and resistance distribution.

  4. Statnamic load test - Wikipedia

    en.wikipedia.org/wiki/Statnamic_load_test

    The Statnamic load test is a type of test for assessing the load-carrying capacity of deep foundations which is faster and less expensive than the static load test.The Statnamic test was conceived in 1985, with the first prototype tests carried out in 1988 through collaboration between Berminghammer Foundation Equipment of Canada and TNO Building Research of the Netherlands.

  5. Structural dynamics - Wikipedia

    en.wikipedia.org/wiki/Structural_dynamics

    A dynamic load can have a significantly larger effect than a static load of the same magnitude due to the structure's inability to respond quickly to the loading (by deflecting). The increase in the effect of a dynamic load is given by the dynamic amplification factor (DAF) or dynamic load factor (DLF):

  6. Dynamic design analysis method - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Design_Analysis_Method

    The dynamic design analysis method (DDAM) is a US Navy-developed analytical procedure for evaluating the design of equipment subject to dynamic loading caused by underwater explosions (UNDEX). The analysis uses a form of shock spectrum analysis that estimates the dynamic response of a component to shock loading caused by the sudden movement of ...

  7. Load testing - Wikipedia

    en.wikipedia.org/wiki/Load_testing

    The governing contract, technical specification or test method contains the details of conducting the test. The purpose of a mechanical load test is to verify that all the component parts of a structure including materials, base-fixings are fit for task and loading it is designed for. Several types of load testing are employed

  8. Four-point flexural test - Wikipedia

    en.wikipedia.org/wiki/Four-point_flexural_test

    The test method for conducting the test usually involves a specified test fixture on a universal testing machine. Details of the test preparation, conditioning, and conduct affect the test results. The sample is placed on two supporting pins a set distance apart and two loading pins placed at an equal distance around the center.

  9. Fatigue testing - Wikipedia

    en.wikipedia.org/wiki/Fatigue_testing

    Fatigue cracks typically initiate from high stress regions such as stress concentrations or material and manufacturing defects. It is important that the test article is representative of all of these features. Cracks may initiate from the following sources: Fretting, typically from high cycle count dynamic loads.
