IMPROVING PROTECTION
The woodpecker, on
average, can hit a tree up to
2500 times a day.
This would be equivalent
for us to receive full
thrown punches from an
opponent2500 times in

“On Impact Mechanisms”
Here is a look at the mechanism of “impact shockwaves being
redirected, then dissipated, by the materials and multi-structures
of the horn.”
These observed multi-forms
,
can be imitated into man made
devices.

Impact.
COALITION BETWEEN SOUND
AND SHOCK IMPACT MECHANISMS
24
EQUAL IMPORTANCE -Therefore the medium’s substance, matter,
structure, shape will influence the shock event when impacted.
GOOD CANDIDATES -Materials that have high sound transfer capability
are good candidates to build devises that would be used for impact redirection.
COMBINE THE REQUIREMENTS -If these materials also have a good
flexural strength, flexural modulus, shape is the last element to master if a
device is to redirect impact energy…
SHIELDS UP -Energy can annul itself if simultaneously two equal sources
impact each other. Add hundred of controlled elements that influence energy’s
direction & speed and high energy mitigations is a possibility.

The below Level IV Ballistic hard armor plate has a lightweight cover, designed
by Mawashi, that protects the ceramic from damage and/or cracking when
dropped or struck during handling and use.
LOAD MANAGEMENT
–DEAD LOAD (weight of the structure acting with gravity)
–LIVE LOADS (imposed loads, are temporary, of short duration, or
moving)
–ENVIRONMENTAL LOADS (changes leading to thermal expansion
cause thermal loads)
–STATIC LOADS (that build up gradually over time)
–DYNAMIC LOADS (display significant dynamic effects)
–LOAD COMBINATION (results when more than one load type acts)
