The safety of Li-ion batteries (LIB) has become an important issue with the continuously
increased use of electric vehicles (EV) in the world. In a survivable vehicle crash, when the …

This paper studies the damage of structural components (solid structures and electronics)
under severe shock environment introduced by intensive impulsive loads. Two types of …

This paper uses analysis and high-speed photography to study the impact tolerance of
cellular phones. Thin-walled clamshell case construction, which is currently favored for …

In this study, we propose an asymmetric bistable shock isolator (BSI) based on a new
concept of repeated force-transfer nullification. The asymmetric BSI, with one potential well …

The “clattering” motion that results when flat objects, like portable electronic products, strike
the ground at an angle, is introduced and studied. During clattering one corner of the …

To evaluate the shock characteristics of critical component for a nonlinear packaging
system, a new concept of three‐dimensional shock spectrum was proposed. Three key …

Conducting drop tests to investigate impact behavior and identify failure mechanisms of
small-size electronic products is generally expensive and time-consuming. Nevertheless …

This study proposes a method to apply dual criteria for the assessment of product damage
based on the deceleration signal in a crash-stop incident. To evaluate the shock effects, a …

The shock response spectrum (SRS) is a tool commonly used by application engineers that
characterizes the severity of a transient acceleration. Due to the definition of the SRS …

Most electronic devices suffer impact-induced failure in their usage. Drop/impact
performance of these products is one of the important concerns in product design. It is often …
