Simulations have clear advantages over physical tests in that they offer repeatable results, provide information (stress, strain, acceleration, etc.) at any point in the model at any time during the analysis, can be performed at less cost, and can be included at any stage in the design process. Assessing the response of a prototype electronic device to shock loading typically involves a combination of laboratory testing and analytical simulation. The ability to withstand such loading is critical to the design of a successful product. Background It is not uncommon for personal electronic devices to be subjected to mechanical shock loading, particularly that associated with being dropped from the hand or falling from a table. Abaqus/Explicit has been used extensively to examine the behavior of electronic devices experiencing mechanical shock loading. The ability to simulate drop-type loading reliably reduces the dependency on experimental testing. Accounting for this loading scenario in the design process, both analytically and experimentally, allows for the development of more durable products. It is inevitable that such devices will occasionally experience the shock loading associated with being dropped. 1 Drop Test Simulation of a Cordless Mouse Abaqus Technology Brief TB-04-DTCM-1 Revised: April Summary Portable, hand-held electronic devices have become commonplace due to their small size and light weight.
