BARRY'S DURABILITY SCALE
https://ibb.co.com/3YVjk82B (image)
Barry Berkman's strength analysis during the explosion of an apartment building.
Location and architectural analysis: 18783 Los Alimos St, Porter Ranch, CA 91326; coordinates: 34.2694, -118.5422; APN: 2717-024-034. According to real estate registers (https://goo.gl/maps/Q4VrtMipzyqhopW38 , https://www.redfin.com/CA/Porter-Ranch/18783-Los-Alimos-St-91326/home/5792060 , https://www.zillow.com/homedetails/18783-Los-Alimos-St-Porter-Ranch-CA-91326/20161517_zpid /), the facility was built in 1978. Type V-N (wood-frame) construction. The frame consists of Douglas Fir-Larch wood, the actual size of the posts is 38x89 mm and 38x140 mm. OSB cladding is 12.7 mm, the outer coating is 3 layers of stucco cement plaster (20-25 mm).
Clarifying the topology and lore (Season 3, Episode 4 "All the sauces"): The initial detonation point of the IED is the technical underground (crawl space) under the house. Barry Berkman personally planted the bomb. Barry was in his car at the time of the detonation. The exact distance from the epicenter of the explosion to the car was determined through Google Maps satellite measurements and is 18.6 meters (measurements are visualized at: 3:23 / 3:59 ). Location confirmed by ENT: https://barry-hbo .fandom.com/wiki/All_the_sauces , https://www.avclub.com/barry-review-season-3-episode-4-all-the-sauces-1848923634
Determination of the total energy of the explosion (Yield): The destruction affected the central part of the foundation and the first floor. With a fracture area of 140 m2 and a height of 3.5 m, the volume of critical fracture (V) is 490 m3. Violent Fragmentation threshold for wood and drywall (https://vsbattles.fandom.com/wiki/References_for_Common_Feats ) is 5,000,000 J/m3.
Total energy (E): 490 * 5000000 = 2 450 000 000 Joules (2,450 MJ, equivalent to 585 kg of TNT).
Overpressure verification (Peak Overpressure): To eliminate any arguments about the empty space inside the building, the calculation of the reduced distance (Z-factor) is applied. At R = 18.6 meters and a charge mass of W = 585 kg of TNT, the Z-factor is 2.22. According to the Kingery-Bulmash tables, the overpressure at this distance reaches 75-80 kPa (about 11 psi). This pressure is guaranteed to destroy car windows and deform steel body panels, and for a person without shelter it is many times higher than the threshold of severe barotrauma and contusions, confirming the superhuman impact environment.
Geometric distribution (Hemispherical Surface Burst): The charge was underground at ground level. The shock wave is reflected from the ground and distributed over the hemisphere. Distance to Barry (r) = 18.6 meters.
Hemisphere area: 2 * 3.14159 * (18.6 * 18.6) = 2173.72 m2.
The area of damage to the upper body in the car interior (A): 0.3 m2.
Basic absorbed energy: (2 450 000 000 * 0.3) / 2173.72 = 338130 Joules (338.13 kJ).
Shielding coefficient: The Pontiac Grand Prix Sedan of the 6th generation (1997-2003, 4-door body, GM W-body platform) is used as an object of calibration and obstacle. According to the technical specifications (https://en.wikipedia.org/wiki/General_Motors_W_platform , https://en.wikipedia.org/wiki/Pontiac_Grand_Prix ), dimensions: length up to 5017 mm, width 1847 mm, height 1390 mm, maximum curb weight — 1614 kg. The body is a classic American unibody. The presence of a central pillar (B-pillar) in the Sedan version, a steel frame and a massive cast-iron V6 cylinder block ensure extreme damping of the kinetic energy of the shock wave. Taking into account the deformation and energy absorption by the barrier: the strict damping coefficient (Lowball) for this type of structure reduces the passage of energy by 50%.
The total kinetic energy acting directly on Barry Berkman's body: 338.13 * 0.5 = 169.06 kJ
