Expert ID: 728327 Virginia, USA

Within the last two decades, Finite Element Analysis (FEA), generally referred to as “Computer Simulations”, provided advanced engineering support for many accident-related cases. FEA can provide a very thorough analysis and deep understanding of the overall accident as well as the performance of each component involved in the accident. For any collision, FEA can precisely calculate and/or predict crucial engineering information in two areas:
(i) Kinematics of the investigated accident (i.e. absolute and relative motion, velocity and acceleration of the different parts involved in the accident), and
(ii) Structural analysis (i.e. deformation, stresses, strains, failures, energy absorbed, etc.) of any part involved in the accident (vehicle, guardrail, post, pipeline, barrier, etc.).

FEA will provide major compelling engineering evidence to unfold the mystery of any crash-related case. It will provide a better understanding of the accident overall as well as which factors contributed most to the severity of the accident. FEA/Computer simulations can provide substantial engineering support to almost all accident-related cases.

Expert's superior computer simulations are guaranteed to provide the technical knowledge necessary to pursue and win complex lawsuits in the following areas:
1. Automobile, Truck, Boat and Motorcycle Crashes,
2. Airbag and Seatbelt Fatalities/Injuries,
3. All Structural Analysis Cases due to Accidents or Blasts,
4. Slip and Fall Cases,
5. Occupant Biomechanics Analysis,
6. Stress, Strain, and Failure Analyses for all Structural Components,
7. Fracture and Fatigue Analysis,
8. Fuel Tanks, Pipelines and Pressure Vessel Analysis,
9. Vehicle Dynamics,
10. Vehicle Crashworthiness,
11. Crash and impact analysis.

In all cases analyzed, expert's FEA provided more comprehensive understanding of the case and major compelling evidence to solve it effectively. The cost of conducting a thorough FEA to analyze any accident is far below any other traditional engineering technique.

In a highway accident, a passenger vehicle impacted a W-beam guardrail where the later separated into two pieces and broke into the vehicle causing a fatality. The lawsuit started almost two years after the accident and the damaged guardrail was already removed and destroyed. The Plaintiff hired Expert to evaluate the guardrail behavior even though the damaged guardrail was no longer available for testing. Expert's computer simulations were able to scientifically prove that a fault-free guardrail will perform differently (unlike the accident guardrail) and should redirect the vehicle again into the main road instead of failing and breaking into the vehicle. His computer simulations proved that the actual guardrail at the accident location was suffering a major fault that prompted its wrong performance during the accident. The computer simulation evidences provided by Expert was so compelling to the Plaintiff and enabled him to settle the case in his favor.In a fatal accident, a med-size passenger vehicle impacted a concrete bridge parapet where the vehicle suffered severe damage/deformation and caught on fire immediately thereafter. The deceased family filed a lawsuit against the county for alleged negligence and it was so important to find out the exact accident speed. The police officer and two different expert witnesses came with three different estimated accident speeds without any solid prove. The Defendant hired Expert who was successfully able to simulate the accident through his physics-based computer modeling and simulations. By comparing the vehicle deformation in the computer simulations with the actual vehicle deformation in the accident, Expert was able to accurately estimate/prove the exact accident speed. Expert's accurate estimation of the accident speed was a major pillar in the Defense strategy.A big tree fell on a high-voltage power transmission line in California causing some damage in the tower structure and cutting few high-voltage cables. The cables fell on the Expert grass, sparked and ignited a big fire that expanded across hundreds of acres. Expert was hired by the California Department of Forestry to analyze the incident and find out whether the high-voltage cables and structural towers acted properly according to its designated capacity/strength or it has an error/fault that was responsible for the cables’ failure and therefore the resulted fire. Through his advanced computer modeling and simulations skills, Expert was able to physically simulate the incident and analyze the behavior of the cables and structural towers when impacted by the tree. He provided convincing scientific evidences showing the kinematics and structural analysis for the high-voltage towers/cables when impacted by the tree. In a regular accident, a med-size passenger vehicle impacted a W-beam guardrail. The driver suffered minor injuries, while the passenger suffered severe injuries and passed away within few hours. The driver indicated that he was driving on about 45 mph speed when he lost control of his vehicle and impacted the guardrail. However, the deformations in the vehicle and guardrail structures seem moderate and do not support the 45 mph impact claimed by the driver. As a result, the police suspected a homicide and wanted to find out what was the exact impact speed for this accident. The traditional engineering techniques were not able to come with an accurate estimation of the impact speed and the only approach left for the police and DA office at that time was to run an actual crash test using the same car and same guardrail. The cost of conducting such test is about $80,000 and more than one test might be necessary to define the exact impact speed of the accident. When the DA office heard about Expert's expertise in conducting accurate FEA/Computer simulations that have physical representation to the actual crash, Expert was hired to conduct the FEA/Computer simulations for the accident in order to accurately estimate the impact speed and direction. Expert's advanced computer simulations were able to provide -and prove- the right answers for less than $10,000.
